The Program in C++ Program to Check If a given number is Deficient or not is given below:
#include <iostream>
using namespace std;
int main() {
int n, sum = 0;
cout << "Hello Codeauri Family,enter a positive integer here to check if it is deficient number or not!:\n ";
cin >> n;
for (int i = 1; i <= n/2; i++) {
if (n % i == 0) {
sum += i;
}
}
if (sum < n) {
cout << n << " is a deficient number" << endl;
} else {
cout << n << " is not a deficient number" << endl;
}
return 0;
}
Output:
Hello Codeauri Family,enter a positive integer here to check if it is deficient number or not!:
22
22 is a deficient number
Pro-Tips💡
This program takes an integer input from the user and then checks if the sum of its proper divisors is less than the given number.
If the sum is less, the number is deficient, otherwise it is not.
