Write a program to check whether a number is even or odd:

1. For even number we check the reminder if reminder is equal to zero so the given number is even otherwise odd.
2. For reminder in c++ we use modulus operator (%). 

         #include <iostream>

         using namespace std;

        int main(){

              int x;

    cout<<"Enter a number: "<<endl;

    cin>>x;

    if(x%2==0){

        cout<<"This is even number: "<<endl;

    }

    else{

        cout<<"This is odd number: "<<endl;

    }

return 0;

 }
