Divide a big number into two parts that differ by k in C++ Program

In this tutorial, we are going to write a program that divides a number into two parts with a difference of k.

Let's see an example.

Input

n = 100
k = 30

Output

65 35

Here, we need to understand a little bit of math before diving into the problem. Let's see it.

We have a + b = n and a - b = k. By adding the two equations, we get

a = (n + k)/2
b = n - a

Example

That's it. We have n and k. And there is nothing more in it. Let's see the code

 Live Demo

#include <bits/stdc++.h>
using namespace std;
void divideTheNumber(int n, int k) {
   double a = (n + k) / 2;
   double b = n - a;
   cout << a << " " << b << endl;
}
int main() {
   int n = 54, k = 12;
   divideTheNumber(n, k);
}

Output

If you run the above code, then you will get the following result.

33 21
