Answer:
#include <iostream>
using namespace std;
void swap(int& m, int& n) /* passing by reference so that changes will be made in the original values.*/
{
int t=m;
m=n;
n=t;
}
int main()
{
int val1,val2;
cout<<"Enter the values"<<endl;
cin>>val1>>val2;
cout<<"Values before swap "<<val1<<" "<<val2<<endl;
swap(val1,val2); //calling the function swap..
cout<<"Values after swap "<<val1<<" "<<val2<<endl;
return 0;
}
Explanation:
Created a function swap with 2 arguments m and n passed by reference.
