Write a Program to Check Whether a Number is Even or Odd

C++ Program to Check Whether a Number is Even or Odd.


In this example,we used if...else statement to check given a number even or odd.

Even number. An even number which number is divided by 2 its called odd number.example 2,6,8,10


Odd number.An even number which number is not divided by 2 its called odd number.example 1,3,5,7,11

Example 1: Check Whether Number is Even or Odd using if or else

#include <iostream>
#include <conio.h>
using namespace std;
int main ()
    {
      int n;

   cout <<"plz enter number";
   cin>>n;

     if (n%2==0)
      cout << "Number is even";
        else
       cout <<"Number is odd";

       return 0;
       getch();
    }

      Output
_________________________
Number is even



Example 2: Check Whether Number is Even or Odd using ternary operators



include <iostream>
#include <conio.h>
using namespace std;
int main ()
    {
      int n;

   cout <<"plz enter number";
   cin>>n;

 (n%2==0)? cout <<"even":
  cout <<number is odd";

    return 0;
      getch ();
    }

output
---------------
Enter the number user
n= 7
number is odd
