Thread: Putting the function body with the prototype

In the code below, I was testing to see if putting the function body with the prototype would work. I'm assuming this makes it inline like it would in a class?

Code:

#include <iostream>

using namespace std;

int mult(int num)
{
  return num*num;
};

int main()
{
  int number;
  cout<<"Input a number. ";
  cin >>number;
  cout<<"That number squared is: "<<mult(number)<<endl;
  system("PAUSE");
  return 0;
}

Only one thing can ask the compiler to inline a function and that is the inline keyword.

Its perfectly ok to put the body with a prototype in the manner you did above. Of course you don't need the ; after the function's closing }

Yeah, but if the semicolon wasn't there, wouldn't that be negating the purpose of the prototype (like if I had three functions up there, to not have to rely on order of declaration)?
