A number is said to be a Spy number if the sum of all the digits is equal to the product of all digits.
Examples :
Input : 1412
Output : Spy Number
Explanation :
sum = (1 + 4 + 1 + 2) = 8
product = (1 * 4 * 1 * 2) = 8
since, sum == product == 8Input : 132
Output : Spy Number
Explanation :
sum = (1 + 3 + 2) = 6
product = (1 * 3 * 2) = 6
since, sum == product == 6
C++
// 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;
