Default arguments.

To write a C++ program to implement functions with default arguments.

Algorithm:

Step 1: Start the program.

Step 2: Declare the function add with default arguments.

Step 3: Call the function with defaults arguments inside the main function.

Step 4: stop the program.

Program Code:

#include<iostream.h>

#include<conio.h>

void add(int=10, int=20)

void main()

{

clrscr();

add();

add(30);

getch();

}

void add(int a, int b)

{

int c;

c=a+b;

cout<<”The value is”<<c<<endl;

}

Output:

The value is 30

The value is 50
