C++ Exercises: Check whether a given number is Abundant or not
C++ Numbers: Exercise-2 with Solution
Write a program in C++ to check whether a given number is Abundant or not.
Pictorial Presentation:
Sample Solution:
C++ Code :
#include <bits/stdc++.h>
using namespace std;
int getSum(int n)
{
int sum = 0;
for (int i=1; i<=sqrt(n); i++)
{
if (n%i==0)
{
if (n/i == i)
sum = sum + i;
else // Otherwise take both
{
sum = sum + i;
sum = sum + (n / i);
}
}
}
sum = sum - n;
return sum;
}
bool checkAbundant(int n)
{
return (getSum(n) > n);
}
int main()
{
int n;
cout << "\n\n Check whether a given number is an Abundant number:\n";
cout << " --------------------------------------------------------\n";
cout << " Input an integer number: ";
cin >> n;
checkAbundant(n)? cout << " The number is Abundant.\n" : cout << " The number is not Abundant.\n";
return 0;
}
Sample Output:
Check whether a given number is an Abundant number: -------------------------------------------------------- Input an integer number: 35 The number is not Abundant.
