Source sentences:
text: Functions can be "called" from the inside of other functions.
text: This calls 'F' using 'fn', assigning the result to the variable 'a' int a = fn ( 'A' ); // This defines 'Call', a function that accepts a pointer-to-'Fn', calls it, and returns the result int Call ( Fn * fn , char c ) { return fn ( c ); } // Call(fn, c) // This calls function 'Call', passing in 'F' and assigning the result to 'call' int call = Call ( & F , 'A' ); // Again, '&' is not required // LEGACY
text: Defining it simply names the function and specifies what to do when the function is called.
text: Functions must be in scope when they are called, but the function declaration can be hoisted (appear below the call in the code), as in this example:
text: There are often cases where a function needs to be called dynamically, or the number of arguments to a function vary, or in which the context of the function call needs to be set to a specific object determined at runtime.
text: What distinguishes them from other objects is that functions can be called.
text: get Binds an object property to a function that will be called when that property is looked up.
text: set Binds an object property to a function to be called when there is an attempt to set that property.
text: A function is a block of code which only runs when it is called.
text: When the function is called, we pass along a first name, which is used inside the function to print the full name:
text: The function MyFunction expects an integer argument to be on the stack or in a register when it is called.
text: A major concern here is the management of privilege and security: whilst the function is called from the operating system, it should not run with the same privilege as the system.
text: They are used for functions that can still be called if they only have reference access (with & ) to their environment.
text: They are used for functions that can still be called if they only have reference access (with ) to their environment.
text: They are used for functions that can be called if they have mutable reference access (with &mut ) to their environment.
text: They are used for functions that can be called if they have mutable reference access (with ) to their environment.
text: They are used for functions that are only called once.
text: In fact, main is the only function called automatically, and the code in any other function is only executed if its function is called from main (directly or indirectly).
text: Ends function addition , and returns the control back to the point where the function was called; in this case: to function main .
text: Then, inside, another local variable is declared (), and by means of the expression, the result ofplusis assigned to; which, for this case, whereis 5 andis 3, means that 8 is assigned toThe final statement within the function:Ends function, and returns the control back to the point where the function was called; in this case: to function.
text: By passing the arguments by value, the function forces a and b to be copies of the arguments passed to the function when it is called.
text: By passing the arguments by value, the function forcesandto be copies of the arguments passed to the function when it is called.
text: This does not change at all the behavior of a function, but is merely used to suggest the compiler that the code generated by the function body shall be inserted at each point the function is called, instead of being invoked with a regular function call.

text: That is why, in all the previous examples of functions, the functions were always defined before the main function, which is the function from where the other functions were called.
text: That is why, in all the previous examples of functions, the functions were always defined before thefunction, which is the function from where the other functions were called.
text: The above-mentioned method is especially useful when one wants to set default criteria so that the function can be called with or without parameters.
text: Because default arguments' values are "filled in" at the call site rather than in the body of the function being called, virtual functions take their default argument values from the static type of the pointer or reference through which the call is made, rather than from the dynamic type of the object supplying the virtual function's body.
text: This seems a little magical (how does R know what the value of y is after the function has been called).
text: This is because every time a function is called, a new environment is created to host execution.
text: A function can be called by appending the arguments in parentheses to the function name, or an empty matched set of parentheses if the function takes no arguments.
text: Then you compile your code and every time your program comes up to the point label, your function is called.
text: But what can you do, if you don't know at build-time which function has got to be called?
text: The first problem is that if somehow this function is called recursively (i.e. this function calls itself, directly or indirectly), the code will probably crash, because this->p will be deleted at the end of the last call, and still probably be used before the end of the first call.
text: It is important to note that a function that exists in the global scope can also be called global function and a function that is defined inside a class is called a member function.
text: While function calls are fast (typically taking much less than a microsecond on modern processors), the overhead can sometimes be significant, particularly if the function is simple and is called many times.
text: Since the function is called many times, without the data from the calling function removed, memory requirements increase significantly.
text: The easiest way to understand overloading is to imagine that the compiler first finds every function which might possibly be called, using any legal conversions and template instantiations.
text: The idea is that we pass a function and expect it to be “called back” later if necessary.
text: Here, we created a function, called check() that can be called as many times as we need to.
text: If a function is to be called only from within the file in which it is declared, it is appropriate to declare it as a static function.
text: The statements inside the function do not get executed until the function is called, and the function definition generates no output.
text: Function definitions do not alter the flow of execution of the program, but remember that statements inside the function are not executed until the function is called.
text: A value provided to a function when the function is called.
