C++  (8) : How to swap two numbers? Using third variable.

Code:

#include<iostream>

using namespace std;

int main(){

double a,b,c;

cout<<"*****Swapping two numbers using third variable.*****"<<endl;

cout<<"Enter first number."<<endl;

cin>>a;

cout<<"Enter second number."<<endl;

cin>>b;

cout<<"The given numbers are:"<<endl;

    cout<<"a = "<<a<<endl;

    cout<<"b = "<<b<<endl;

    c=a;

    a=b;

    b=c;

cout<<"The numbers after swapping."<<endl;

    cout<<"a = "<<a<<endl;

    cout<<"b = "<<b<<endl;

return 0;

}

Output:

*****Swapping two numbers using third variable.*****

Enter first number.

10

Enter second number.

The given numbers are:

a = 10

b = 5

The numbers after swapping.

a = 5

b = 10
