Re: [Dev-C++] FunctionCalling()

[Rafael C. <rc...@un...>]

You should use prototypes to define the functions you need
in your main function.=20
Define your prototypes before the main function or
in another file (.h). The code for your functions=20
can be after your "main".

In your case, the prototypes would be:
void FuctionOne(void);
void FuctionTwo(void);

Basically, they are the headers of functions with
a ";" at the end.

So you have, for instance:
1) prototypes
void f1 (void);
void f2 (int);

2) main function
void main() {
...
  f1();
  f2("an integer");
...
}

3) implementation of the functions you define
void f1 (void) {
  int myInt;=20
...
  f2(myInt);
...
}

void f2 (int anInt) {
...
}
