[Dev-C++] Dev - C++ function syntax problem

[Peter C. <pet...@li...>]

Hello  I  started learning C++ a week ago, and was beginning to think it 
wasn't half as difficult as it's made out to be.  Then I tried a minimalist 
program to demonstrate the syntax of calling a function.

With the program below I get the compiler message " parse error before 
'{'  " relating to opening curly bracket of return s1* s2.  Any ideas about 
what is wrong, nothing I do cures it.

#include <iostream.h>
int area( int s1, int s2);
int main()
{
int vol;
vol = area(12, 13);
int area( int s1, int s2 )
{
return s1*s2;
}
return 0;
}

try to declare function out of the main.

ex.

#include <iostream>

using namespace std;

int area( int s1, int s2);

int main()
{
  int vol;
  vol = area(12, 13);
  cout << "area(12, 13): " << vol << endl;
  return 0;
}

int area( int s1, int s2 )
{
  return s1*s2;
}

If debugging is the process of removing bugs,
then programming must be the process of putting them in.

You can't define a function within a function. here you define area()
inside main().

Proper ANSI C++ code:

int area( int s1, int s2);

int main()
{
 int vol;
 vol = area(12, 13);

 return 0;
}

int area( int s1, int s2 )
{
 return s1*s2;
}
