Odd Even Program in C

Odd-Even program in C:

An even number is perfectly divisible by 2, whereas an odd number is not perfectly divisible by 2.

We use this logic to check if a number is even or odd.

The below code checks if the integer entered by the user is even or odd:

#include <stdio.h>
int  main()
{
int  number;
printf("Enter an integer: ");
scanf("%d", & amp; number);
if (number % 2  == 0)
  printf("%d is even.", number);

else
  printf("%d is odd.", number);

return  0;
}

• We have created an integer variable number to store the user input.
• We are checking if the integer entered by the user is perfectly divisible by 2 or not. If it is, then it is an even number; else, it is an odd number.
• We use the modulus operator to check for divisibility. If a%b is equal to 0, it implies that a is perfectly divisible by b.

We run the code for different inputs and get the outputs accordingly.

Some inputs and outputs for the code are:

Enter an integer:  4
4 is even.
Enter an integer:  5
5 is odd.
Enter an integer:  -54
-54 is even.
Enter an integer:  12223
12223 is odd.
