# Answer to Question #45936 in C++ for Enrique

Question #45936

calculations.

A number is called perfect if the sum

of its divisors is equal to the original number. A number is

called deficient if the sum of its divisors is less than the

original number. A number is called abundant if the sum

of its divisors is more than the original number. Write a

program that answers the following questions: What

numbers below 5000 are perfect? What odd numbers

below 5000 are abundant? What are the relative

proportions of deficient, abundant, and perfect numbers?

5000 should be in a global constant.

Expert's answer

`#include <iostream>`

using namespace std;

const int MAX_NUM = 5000;

int sum_of_divisors(int n) {

int sum = 0;

for (int i = 1; i < n; ++i) {

if (n % i == 0) sum += i;

}

return sum;

}

int main() {

int perfect = 0, deficient = 0, abundant = 0, odd_abundant = 0;

for (int i = 1; i <= MAX_NUM; ++i) {

int sum = sum_of_divisors(i);

if (i == sum) {

cout << "Number " << i << " is perfect" << endl;

++perfect;

}

else if (i < sum) {

cout << "Number " << i << " is abundant" << endl;

++abundant;

}

else {

cout << "Number " << i << " is deficient" << endl;

++deficient;

}

if ((i < sum) && (i % 2 == 1)) {

cout << "Number " << i << " is odd abundant" << endl;

++odd_abundant;

}

}

cout << "A number of deficient, odd_abundant, abundant, perfect: "

<< deficient << ":" << odd_abundant << ":" << abundant << ":" << perfect << endl;

cout << "Relative proportion of deficient, odd_abundant, abundant, perfect: "

<< (float) deficient/(float) MAX_NUM << ":" << (float) odd_abundant/(float) MAX_NUM << ":" << (float) abundant/(float) MAX_NUM << ":" << (float) perfect/(float) MAX_NUM << endl;

}

ricky15.09.14, 22:06When you run this program it only gives you 1 perfect number and I know there is more than one perfect number . How do you fix it ?
