#include iostreamusing namespace std;void swapint& a int& b int temp = a; a = b; b = temp;int main int x y; cin x y; cout a= x b= y endl; swapx y; cout a= x b= y

The program takes two integers as input, swaps their values using a swap function, and then prints the new values.

For example, if the input is:

3 5

The output will be:

a=3 b=5
a=5 b=3
