- Write a C program to check whether it is odd or even number using switch case statement.
- How to check a number is odd or even in C.

Required Knowledge

- C printf and scanf functions
- Switch case statement in C

Any numbers divisible by 2 are even numbers whereas numbers which are not divisible by 2 are odd numbers. Any even number can be represented in form of (2*N) whereas any odd number can be represented as (2*N + 1). Even Numbers examples: 2, 6 , 10, 12 Odd Number examples: 3, 5, 9 ,15

### C program to check a number is Even of Odd using switch case statement

#include <stdio.h> #include <conio.h> int main() { int num; /* Take a number as input from user using scanf function */ printf("Enter an Integer\n"); scanf("%d", &num); switch(num%2) { /* Even numbers completely are divisible by 2 */ case 0: printf("%d is Even", num); break; /* Odd numbers are not divisible by 2 */ case 1: printf("%d is Odd", num); break; } getch(); return 0; }

Output

Enter an Integer 8 8 is Even

Enter an Integer 5 5 is Odd
