Welcome Programmer: Even and Odd Program in C++

In general Even numbers are those which are divisible by 2, and which numbers are not divisible 2 is called Odd number.

But in term of programming for find even number we check remainder of number is zero or not, If remainder is equal to zero that means number is divisible by 2. To find remainder of any number we use modulo (%) operator in C language which return remainder as result.

Check give number is Even or Odd

#include<iostream.h>
#include<conio.h>

void main()
{
int no;
clrscr();
cout<<"Enter any num: ";
cin>>no;
if(no%2==0)
{
cout<<"Even num";
}
else
{
cout<<"Odd num";
}
getch();
}

Output

Enter any num : 5
Odd num

Check give number is Even or Odd Using ternary or conditional Operator

Example

#include<iostream.h>
#include<conio.h>

void main()
{
int no;
clrscr();
cout<<"Enter any num : ";
cin>>no;
(no%2==0) ? cout<<"Even num"; : cout<<"Odd num";
getch();
}

Output

Enter any num : 6
Even num

Check give number is Even or Odd Using Bitwise Operator

Example

#include<iostream.h>
#include<conio.h>

int main()
{
  int num;
  clrscr();
  cout<<"Enter any num: ";
  cin>>num;
  if(num & 1)
  {
  cout<<num<<" is odd";
  }
  else
  {
  cout<<num<< <<" is even";
  }
  getch();
}
