Program to check whether the given number is Buzz Number or not in C++

Given with a number ‘n’ and the task is to determine whether the given positive integer is a buzz number or not and display the result as an output.

What is Buzz Number?

For being a buzz number there are two conditions either of which must be true −

• Number should end with digit 7 e.g. 27, 657, etc.

• Number should be divisible by 7 e.g 63, 49, etc.

Input

number: 49

Output

it’s a buzz number

Explanation − since the number is divisible by 7 so it’s a buzz number

Input

number: 29

Output

it’s not a buzz number

Explanation − since the number is neither divisible by 7 nor end with digit 7 so it’s not a buzz number

Approach used in the given program is as follows

• Input the number to check for the condition

• Check whether the number is ending with digit 7 or divisible by 7

• If the condition holds true print its a buzz number

• If the condition doesn’t holds true print its not a buzz number

Algorithm

Start Step 1→ declare function to check if a number is a buzz number of not    bool isBuzz(int num)       return (num % 10 == 7 || num % 7 == 0) Step 2→ In main()    Declare int num = 67    IF (isBuzz(num))       Print "its a buzz Number\n"    End    Else       Print "its not a buzz Number\n"    End Stop

Example

 Live Demo

#include <cmath> #include <iostream> using namespace std; // function to check if its a buzz number bool isBuzz(int num){    return (num % 10 == 7 || num % 7 == 0); } int main(){    int num = 67;    if (isBuzz(num))       cout << "its a buzz Number\n";    else       cout << "its not a buzz Number\n"; }

Output

If run the above code it will generate the following output −

its a buzz Number
