Write A Program To Check Entered Number Is A Spy Number Or Not Through C++ Program

In this post I am going to discuss a program called, Entered Number A Spy Number Or Not Through C++ Program.

What is a Spy Number?

When you enter a natural number like 1124 then sum up its digit is equal to the product of all the digits. Like,

//Example:
Suppose n=1124
Product of digits on prod=(1 * 1 * 2 * 4) = 8
Sum of digits on sum=(1 + 1 + 2 + 4) = 8
Here, sum==prod both product and sum are equal.
Output: Spy Number

Input : 1412
Explanation : 
sum = (1 + 4 + 1 + 2) = 8
product = (1 * 4 * 1 * 2) = 8
since, sum == product == 8
Output : Spy Number

Input : 132
Explanation : 
sum = (1 + 3 + 2) = 6
product = (1 * 3 * 2) = 6
since, sum == product == 6
Output : Spy Number

C program to check number is a spy number or not:

// CPP program to check
// a spy number
#include <bits/stdc++.h>
using namespace std;

// Function to
// check spy number
bool checkSpy(int num)
{
	int digit, sum = 0,
		product = 1;
	while (num > 0)
	{
		digit = num % 10;
		
		// getting sum of digits
		sum += digit;
		
		// getting product of digits
		product *= digit;
		num = num / 10;
	}
	
	if (sum == product)
		return true;
	else
		return false;
}

// Driver code
int main()
{
	int num = 1412;
	if (checkSpy(num))
		cout << "The number is "
			<< "a Spy number"
			<< endl;
	else
		cout << "The number is "
			<< "NOT a spy number"
			<< endl;
	return 0;
}
Case-1:
The number is a Spy number
