C++ Exercises: Check whether a number is a Strong Number or not
C++ Numbers: Exercise-45 with Solution
Write a program in C++ to check whether a number is a Strong Number or not.
Sample Solution:
C++ Code:
#include <iostream>
using namespace std;
int main()
{
int i, n, n1, s1 = 0, j;
long fact;
cout << "\n\n Check whether a number is Strong Number or not:\n";
cout << "----------------------------------------------------\n";
cout << " Input a number to check whether it is Strong number: ";
cin >> n;
n1 = n;
for (j = n; j > 0; j = j / 10) {
fact = 1;
for (i = 1; i <= j % 10; i++) {
fact = fact * i;
}
s1 = s1 + fact;
}
if (s1 == n1) {
cout << n1 << " is Strong number." << endl;
}
else {
cout << n1 << " is not a Strong number." << endl;
}
}
Sample Output:
Check whether a number is Strong Number or not: ------------------------------------------------------- Input a number to check whether it is Strong number: 24 24 is not a Strong number
