Question: What is the difference between an array declared as static, and one that is not?
Instructor answer: The arrays declared as static live throughout the life of the program; that is, they are initialized only once, when the function that declares the array it is first called.

Student answer: a static array will store the new values that were assigned to each of its elements. meaning if you call a function twice it will use the last values that were returned the first time.  if you don't declare it static then the new values will not be stored and will be reset to their original value
Grade (0-5): 5

Student answer: a static array can only be referenced not accessed. Also static arrays can be used without creating an object.
Grade (0-5): 4

Student answer: An array declared as static is not created and and initialized each time the function and it is also not destroyed when the function terminates.
Grade (0-5): 5

Student answer: A program intializes static local arrays when their declarations are first encountered.  If a static array is not initialized explicityly by the programmer, earch element of that array is intialized to zero by the compiler when the array is created.  Non-static array members cannot be initialized at all in C++.
Grade (0-5): 4

Student answer: Arrays that are static remain the same size throughout the program execution.
Grade (0-5): 4

Student answer: a static array will only be initilized once, a non static array will be re-initilized once the program reaches the initilization line again.
Grade (0-5): 5

Student answer: An array declared as static is available from beginning of program to end. One w/o static declaration disappears if it is not accessed within the right scope.
Grade (0-5): 4.5

Student answer: a static array has pre-runtime size and that size cannot be changed. A dynamic array gets its size at runtime.
Grade (0-5): 3

Student answer: If an array is declared as static, it is not created each time the array is called.
Grade (0-5): 5

Student answer: An array that is not declared as static will re-initialize every time the function declaring it is called. A static array will initialize only once, at the declaration, and will store the values in it's elements throughout the duration of the program, even if the same function is called multiple times, a static array will only initialize once.
Grade (0-5): 5

Student answer: All elements are initialized to zero if not explicitly initialized, this does not happen for automatic local arrays<br><br>
Grade (0-5): 4.5

Student answer: All elements are initialized to zero if not explicitly initialized for a static array, while a non-static array is not initialized to zero.
Grade (0-5): 4.5

Student answer: static cannot be changed
Grade (0-5): 3

Student answer: A static array has a set size that cannot change. The data may not need all of the space assigned, or could go beyond the size.
Grade (0-5): 4

Student answer: A static member prevents naming conflicts (not put into global namespace) while allowing for information hiding (private, public).
Grade (0-5): 3
Question: What is the difference between an array declared as static, and one that is not?
Instructor answer: The arrays declared as static live throughout the life of the program; that is, they are initialized only once, when the function that declares the array it is first called.

Student answer: A static local array exists for the duration of the program and its elements are initialized to 0 if not explicitly initialized. So a static local array's elements will still be the same when called later unless specifically initialized to something else.  This doesn't happen for automatic arrays.
Grade (0-5): 5

Student answer: Static arrays are those with a declared size, that is known to the program, whereas non-static arrays leave the size undeclared and open so it can be assigned later. Usually used for input purposes.
Grade (0-5): 3

Student answer: static arrays keep the values after the end of a function, while non static reinitialize every time.
Grade (0-5): 5

Student answer: Static arrays are created and initialized only once, and the values aren't destroyed <br>when the function terminates in the program.<br>Automatic arrays reset everytime the function is called.
Grade (0-5): 5

Student answer: its not created and initialized each time program calls the function, and is not destroyed every time the function ends in the program.
Grade (0-5): 5

Student answer: When we declare it static the array is not destroyed after the function is over.  When an array is not declared as static, the array is created and initialized every time a function calls it.
Grade (0-5): 5

Student answer: the static array exists for the duration of the program<br>
Grade (0-5): 4.5

Student answer: an array declared as static can only be declared once
Grade (0-5): 3.5

Student answer: A static array exists in memory until the program terminates, whereas an automatic (or normal) array is removed when the function that created it terminates
Grade (0-5): 5

Student answer: not answered
Grade (0-5): 0

Student answer: Only constants can be used to declare the size of automatic and static arrays<br>Exists for the duration of the program<br>Is initialized when its declaration is first encountered<br>All elements are initialized to zero if not explicitly initialized<br>
Grade (0-5): 5

Student answer: A static array cannot be changed in the program.
Grade (0-5): 3

Student answer: static arrays are available throughout the program
Grade (0-5): 5

Student answer: a static array is allocated when the program starts and is freed when the program exits but has limited scope, while an array that is not declared static is allocated and freed when it comes into and out of scope.
Grade (0-5): 5

Student answer: if they are declared fixed or static that means they can't change size once their storage has been allocated, however one that is not or dynamic arrarys can be resized.

Student answer: when passing (in main) a multidimensional array to a function, no dimensions need be specified
Grade (0-5): 2

Student answer: All dimensions except for the first one need to be specified when passing an array to a function, the compiler needs to know how many memory addresses to skip to make it back to the 2nd element in the first dimension.  The size of the first dimension does not need to be specified.
Grade (0-5): 5

Student answer: as many as there are dimensions. Most commonly just rows and columns
Grade (0-5): 3.5

Student answer: at least 2, but it should always equal the number of dimensions that the argument is expecting... like... <br>blah[][][][] will require 4 dimensional array input.<br>blah[][][] will require a 3 dimensional array.<br>blah[][] will require a 2 dimensional array.

Question: In one sentence, what is the main idea implemented by insertion sort?
Instructor answer: Taking one array element at a time, from left to right, it inserts it in the right position among the already sorted elements on its left.

Student answer: Takes an element of an array and compares it with the next element, depending on the values of the two elements they will switch and then the program will compare the new switched element with the next one in the array.
Grade (0-5): 3

Student answer: Insertion sort divides the list into sorted and unsorted regions, then takes each item from the unsorted region and inserts it into its correct order in the sorted region.
Grade (0-5): 5

Student answer: The sorted array or list is built one entry at a time.
Grade (0-5): 3.5

Student answer: It starts with the second element and checks it to see if it is less than the element(s) to the left of it and if it is it inserts it into its corrected position.

Student answer: a comparison sort in which the sorted array is built one entry at a time
Grade (0-5): 4

Student answer: Insertion sort is an algorithm where the first element of the array is in the sorted list, all the other pick one by one and taken from the unsorted array, to the sorted array.
Grade (0-5): 4.5

Student answer: Every iteration of an insertion sort takes away an element from the input data, inserting it at the right position in the sorted list.
Grade (0-5): 5

Student answer: the insertion sort creates a new array and inserts each item in its place with respect to the new array.
Grade (0-5): 4

Student answer: Insertion sort takes each entitity of an unsorted array in order, and sorts it into the correct position between the entities it has sorted.
Grade (0-5): 5

Student answer: it takes the second element and swaps it with the 1st if it is less and keeps it there if its larger, then it goes to the third element and inserts it in the right places with respect to the first 2 elements and so on...
Grade (0-5): 5

Student answer: Starting with the first element in the array, each following element is put in place by determining if it is smaller or larger than the starting element.
Grade (0-5): 4

Student answer: one by one, each item is taken and placed into the correct place in the sorted portion of the array until there are no more items
Grade (0-5): 4.5

Student answer: you take each element and insert it in the correct position with respect to all the elements before it
Grade (0-5): 5

Grade (0-5): 4
Question: In one sentence, what is the main idea implemented by selection sort?
Instructor answer: Taking one array element at a time, from left to right, it identifies the minimum from the remaining elements and swaps it with the current element.

Student answer: Searches an array for the largest or the smallest element and is moved out to the front of the array then it will search for the next largest or the smallest element to move out to the front
Grade (0-5): 5

Student answer: Selection sort searches the whole array for the largest item and puts it at the end of the array, then searches for the second largest item and puts it at the second to last spot and so on.
Grade (0-5): 4.5

Student answer: Finds the minimum value and swap it with the value in the first position.
Grade (0-5): 5

Student answer: It finds the minimum element in the array and swaps it with the first element then repeats this step swapping the minimum element with nth positions in the array.

Question: What is the number of operations for insertion sort under a best-case scenario, and what is the best-case scenario?
Instructor answer: N (the length of the array) operations achieved for a sorted array.

Student answer: The run time for this sorting program is n^2.  Best case is the list is already sorted, worst case is the list is sorted but in reverse.
Grade (0-5): 3.5

Student answer: Insertion sort is O(n) and performs n-1 operations in the best-case scenario, which is when the list or array is already sorted.
Grade (0-5): 4.5

Student answer: The number of operations for insertions sort, under best-case, is  n(n-1)/2. The best case for insertion sort is on a sorted list where it runs is O(n).
Grade (0-5): 3

Student answer: Best case would be O(n) or n-1, because that's what it takes to scan the array and make one swap. The array would then be sorted and would take only 1 operation.
Grade (0-5): 4

Student answer: Best case-1<br>Worst Case-N
Grade (0-5): 2

Student answer: It will do (n) operations where (n) is the number of elements in the array. Best case is when all the elements are already sorted.
Grade (0-5): 5

Student answer: O(n)
Grade (0-5): 3.5

Student answer: Best case is all elements sorted.<br>n-1.
Grade (0-5): 4

Student answer: The best case scenario for an insertion sort, where all the elements of the array have been already sorted, will cause the for loop to iterate "x" times ("x" being the number of elements in the array) and the while loop to never have to iterate, resulting in the insertion sort to require "x" operations.
Grade (0-5): 5

Student answer: 1 operation. the best case scenario s where it is already sorted and does one comparision.
Grade (0-5): 3

Student answer: n operations, where n is the number of items.
Grade (0-5): 4

Student answer: n-1
Grade (0-5): 3.5

Student answer: O(n), the list is already sorted.
Grade (0-5): 4.5

Student answer: Insertion sort will take n-1 operations if the array is in reverse order.
Grade (0-5): 4

Student answer: In the best case scenario of an already sorted list, insertion sort will progress once through the list.  So the number of operations is directly proportional to the number of elements in the list.  Also noted as O(n) in big o notation.<br>
Grade (0-5): 5

Student answer: 1 where there is a list of two ints and only one must be moved.
Grade (0-5): 2.5

Grade (0-5): 3

Student answer: O(n)
Grade (0-5): 3.5

Student answer: N number of times.  Where N equals the number of elements in the list.  Best-case scenario is that the elements in the list are already sorted.
Grade (0-5): 5

Student answer: the best case scenario for insertion sort is a list that is already sorted. the number of operations would be the same as the number of elements
Grade (0-5): 5
Question: What is the number of operations for insertion sort under a best-case scenario, and what is the best-case scenario?
Instructor answer: N (the length of the array) operations achieved for a sorted array.

Student answer: insertion sort will make zero operations (and length - 1 comparisons) in the best case scenario, that is, when the array its given is already in order.
Grade (0-5): 3.5

Student answer: theta(n)<br>the best case senario is that everything is already sorted
Grade (0-5): 4.5

Student answer: n operations<br><br>The best case scenario is when all the numbers are in increasing order.
Grade (0-5): 5

Student answer: it could be considered that having only one item would be the easiest to sort, but this could also be a trivial result as nothing is moved<br><br>having two items allows the algorithm to sort the items into the correct order
Grade (0-5): 2.5

Student answer: the best case is if it only has to look through the list once. The best case scenario is when it goes through the list and doesn't have to make any changes (the list is already sorted)
Grade (0-5): 4

Student answer: very simplistic it moves one element from the list by one and inserting them in their correct position into a new slot then starting over. best case is (0)1
