Find two numbers with sum and product both same as N in C++

C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to find two numbers with sum and product both same as N.

For this we will be provided with an integer value. Our task is to find two other integer values whose product and sum is equal to the given value.

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
//finding a and b such that
//a*b=N and a+b=N
void calculateTwoValues(double N) {
   double val = N * N - 4.0 * N;
   if (val < 0) {
      cout << "NO";
      return;
   }
   double a = (N + sqrt(val)) / 2.0;
   double b = (N - sqrt(val)) / 2.0;
   cout << "Value of A:" << a << endl;
   cout << "Value of B:" << b << endl;
}
int main() {
   double N = 57.0;
   calculateTwoValues(N);
   return 0;
}

Output

Value of A:55.9818
Value of B:1.01819
