7.1.1.This program contains two functions: main() and f().

#include <iostream> 

using namespace std; 

 

void f(); // f's protoype 

 

int main() 

{ 

  cout << "In main()\n"; 

 

  f(); // call f() 

 

  cout << "Back in main()\n"; 

 

  return 0; 

} 

 

// This if the function's definition. 

void f() 

{ 

  cout << "Inside f()\n"; 

}
