I assume your friend thinks youâre batty because of your beverage opinions and not for other reasons beyond my expertise. Given that, Iâd have to side with your Perrier-drinking pal, but also assure you that it is a common misconception that carbonation pulls calcium from your bones.
Functions [edit]. A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
Calling a Function. While creating a C function, you give a definition of what the function has to do. To use a function, you will have to call that function to perform the defined task. When a program calls a function, the program control is transferred to the called function.
