Check odd or even number
“Check odd or even number” is a very basic programming exercise problem for beginners. Here, we are given a number, entered by user and our task is to write a program to check whether a given number is even or odd.
Even number: A number which is divisible by 2.
Odd number: A number which is not divisible by 2.
Example (Check odd or even number):
INPUT: Number = 4 OUTPUT: 4 is even number INPUT: Number = 7 OUTPUT: 7 is odd number.
We can simply check the divisibility condition to check whether a number is even or odd.
C++ Program to check odd or even number is as follows:
#include<bits/stdc++.h>
using namespace std;
int main()
{
int num;
//Scan the number
cout<<"Enter the number:";
cin>>num;
// Even : Divisible by 2
if(num % 2 == 0)
{
cout<<num<<" is even number";
}
// Odd : Not Divisible by 2
else if(num % 2 != 0)
{
cout<<num<<" is odd number";
}
}
OUTPUT: Enter the number: 4 4 is even number
