To Check Whether a Number is Even or Odd

C Program to Check Whether a Number is Even or Odd Numbers perfectly divisible by 2 are known even numbers and numbers which are not divisible by 2 are called odd numbers. This program takes an integer from user and checks whether that number is even or odd and displays the result. Source Code /*to check whether a number entered by user is even or odd. */ #include <stdio.h> int main() { int num; printf( "Enter an integer you want to check: " ); scanf( "%d" ,&num); if ((num% 2 )== 0 ) /* Checking whether remainder is 0 or not. */ printf( "%d is even." ,num); else printf( "%d is odd." ,num); return 0 ; } Output 1 Enter an integer you want to check : 25 25 is odd . Output 2 Enter an integer you want to check : 12 12 is even .   In this program, user is asked to enter an integer which is stored in variable num . Then,...
