C program for even or odd using for loop

• If a number is divisible by 2 then it is an even number.
• If a number is not divisible by to it is an odd number.
• To check even or odd number in c we just need to check that using one if condition.
• If if condition of number%2 returns true then it is even number other wise it is odd number.
• Let us see an example c program to check a given number is even or odd without using any recursive function.

Program #1: write a c program to check a number is even or odd without using recursive function.

1. #include <stdio.h>
2. #include <stdlib.h>
3.  
4. int main(int argc, char *argv[])
5. {
6.   
7.   int number;
8.  
9.     printf("Enter a nuber to check even or odd");
10.     scanf("%d", &number);
11.  
12.     // returns true if number is divisible by 2: even
13.     if(number % 2 == 0)
14.         printf("%d is even.", number);
15.     else
16.         printf("%d is odd.", number);
17.  
18. getch();
19.  
20. }

   Output:

Program #2: write a c program to check a number is even or odd without using if condition
