C++ program to convert degree to radian and vice versa

C++ program to convert degree to radian and vice versa. First program converts degree to radian and second program converts radian to degree and in third program to convert degree to radian and vice versa using class.

C++ program to convert degree to radian

#include<iostream>
using namespace std;
int main()
{
    float rad,degree;
    cout<<"Enter the value in degree ";
    cin>>degree;
    rad=degree*22/(180*7);
    cout<<degree<<" degree = "<<rad<<" radian";
    return 0;
}

OUTPUT

C++ program to convert radian to degree

#include<iostream>
using namespace std;
int main()
{
    float rad,degree;
    cout<<"Enter the value in radian ";
    cin>>rad;
    degree=rad*180*7/22;
    cout<<rad<<" rad = "<<degree<<" degree";
    return 0;
}

OUTPUT
