C Program to Check if a given Integer is Odd or Even

This C Program checks if a given integer is odd or even. Here if a given number is divisible by 2 with the remainder 0 then the number is even number. If the number is not divisible by 2 then that number will be odd number.

Here is source code of the C program which checks a given integer is odd or even. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

11.     scanf("%d", &ival);

12.     remainder = ival % 2;

13.     if (remainder == 0)

14.         printf("%d is an even integer\n", ival);

15.     else

16.         printf("%d is an odd integer\n", ival);

$ cc pgm4.c
$ a.out
Enter an integer : 100
100 is an even integer
 
$ a.out
Enter an integer : 105
105 is an odd integer
