Definition
A function is a subroutine to which one or more of the following apply:
- it receives parameters
- it acts on the parameters
- it processes data located elsewhere
- it returns a value
A function does not create a new thread, and therefore the process which called the function waits until the function is completed before continuing executing its code.
As opposed to a process, a function doesn't have a frame; statement. See process for more information.
For a list of functions, see this list of functions.
Example
int addInts( int a , int b )
Begin
return a+b;
End
addInts(3,6); will return 9. One can see that the function does indeed:
- receive parameters.
- act on the parameters.
- return a value.
