Check whether the given number is buzz number or not

A buzz number is a number that either ends with the digit 7 or is divisible by 7. To check whether a given number is a buzz number or not, follow these steps:

  1. Check if the last digit of the number is 7. If yes, then the number is a buzz number.

  2. If the last digit of the number is not 7, then check if the number is divisible by 7. To check if a number is divisible by 7, you can use the following rule:

    • Take the last digit of the number, double it, and subtract it from the remaining digits.
    • If the result is divisible by 7, then the original number is also divisible by 7.

  3. If the number is divisible by 7, then it is a buzz number. If not, then it is not a buzz number.

Program Solution

// C program for 
// Check whether the given number is buzz number or not
#include <stdio.h>

void isBuzzNo(int number)
{
	if (number % 7 == 0 || number % 10 == 7)
	{
		// When last digit is 7  
		// or number is divisible by 7
		printf(" Number %d is buzz number\n", number);
	}
	else
	{
		printf(" Number %d is not buzz number\n", number);
	}
}
int main(int argc, char
	const *argv[])
{
	// Test Cases
	isBuzzNo(126);
	isBuzzNo(123);
