Thread: calling function & called function

Uh, where to begin.

First of all, main() should return an int, and probably receive void:

Code:

int main(void)

Secondly, you are defining a function cts() inside of main(). You aren't supposed to do that. You might want something like this as your function definition:

Code:

void cts(void)
{
    printf(" hi ");
}

printf(" hi ");

}
}

In C any function can not be defined inside any other function's definition. But it can be declared inside other function.

Second cts() starts the definition of the function and thus no need to put a semicolon. Function definitions dont have an ending semicolon but declarations have.
