7.6.1.Demonstrate default arguments

#include <iostream>  

using namespace std;  

 

void f(int x = 0, int y = 100); 

 

int main()  

{  

  f(1, 2); 

 

  f(10); 

 

  f(); 

 

  return 0; 

} 

 

void f(int x, int y) 

{ 

  cout << "x: " << x << ", y: " << y << "\n"; 

}

x: 1, y: 2
x: 10, y: 100
x: 0, y: 100
