This was the program I wrote to challenge the requirement for an entry code to CSC 142, because I had not had the prerequisite CSC 110/Introduction to Programming n Python class.

After I wrote the program to the following spec, I got feedback from the instructor:

"Looks good. It would have better if there was a main function, rather than having that code in "global space". In any case, you demonstrated sufficient background in programming basics to get an entry code. I look forward to meeting you later this month."

so I went out and learned how to do a main() function before writing my next Python program.

For some reason, this works in Python 2.7, but dies in Python 3.4. Not the highest priority (yet), but I do want to figure that out sometime.

CSC 142 challenge:

The CSC 110 prerequisite is more important. In this course, we present the basics of programming: variables, data types, functions, parameters, return values, flow-of-control constructs, multi-value variables (arrays). I expect students to have this information well in hand when they "walk through the door" to CSC 142. Please note, this is quite different than CSE 142 at UW, Seattle. They have no prerequisite programming course. At North Seattle, we found our student success rate was very low, so we added the precursor class. It has been very successful in preparing our students for transfer to the four-year programs in the area.

I ask students who want to challenge the CSC 110 prerequisite to complete a simple programming task. The specifications follow:

Write a simple program in the computer programming language of your choice. The program shall have two functions (methods): a main function and a helper function.

The main function shall do the following:
 * declare an array that holds 10 integer values
 * use a loop to put the integer values 1, 2, 3, ..., 9, 10 into the array
 * pass the array to the helper function which will return an integer value
 * print out the value returned by the helper function.

The helper function shall do the following:
 * traverse the parameter array adding the values found in that array 
 * return the sum of the values.

The whole program should print out the value 55.
