Even or Odd

Even or Odd

Even numbers are those which are divisible by 2, and which numbers are not divisible 2 is called odd numbers.

But in term of programming for find even number we check remainder ofnumber 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 langauge which return remainder as result.

Check give number is Even or Odd

/***************************************************************
       Check give number is Even or Odd
***************************************************************/
#include< stdio.h>
#include< conio.h>
void main()
{
int no;
clrscr();
printf("Enter any number : ");
scanf("%d",&no);
if(no%2==0)
{
printf("Even number");
}
else
{
printf("Odd number");
}
getch();
}

Output

Enter any number : 5
Odd number

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

/**********************************************************

#include< stdio.h>
#include< conio.h>
void main()
{
int no;
clrscr();

scanf("%d",&no);
(no%2==0) ? printf("Even number") : printf("Odd number");
getch();
}

Output

Enter any number : 6
Even number

Check give number is Even or Odd Using Bitwise Operator

/***************************************************************
       Check give number is Even or Odd
***************************************************************/
#include< stdio.h>
#include< conio.h> 
int main()
{
  int num;
  clrscr();
  printf("Enter any number : ");
  scanf("%d",&num);
  if(num & 1)
  {
  printf("%d is odd",num);
  }
  else
  {
  printf("%d is even",num);
  }
  getch();
}

Output

Enter any number : 20
20 is even
