C Program to Find whether a number is Buzz Number or Not


The following example shows, how to find whether a number is a Buzz Number.

  • Takes an integer input from the user.
  • Checks if the number is divisible by 7.
  • If not divisible, checks if the number ends with 7.
  • Prints whether the number is a Buzz number or not.

Example : pgm.c

#include <stdio.h>

int main() {
    int num;

    // Input a number
    printf("Enter a number: ");
    scanf("%d", &num);

    // Check for Buzz number using nested if
    if (num % 7 == 0) {
        printf("%d is a Buzz Number (divisible by 7).\n", num);
    } else {
        if (num % 10 == 7) {
            printf("%d is a Buzz Number (ends with 7).\n", num);
        } else {
            printf("%d is not a Buzz Number.\n", num);
        }
    }

    return 0;
}

Output:

Enter a number: 27
27 is a Buzz Number (ends with 7).

Enter a number: 49
49 is a Buzz Number (divisible with 7).

Enter a number: 23
23 is not a Buzz Number.
