# C++ code to find composite numbers whose difference is n

Suppose we have a number n. We have to find two composite integers (non-prime) a and b, such that a - b = n.

So, if the input is like n = 512, then the output will be 4608 and 4096

## Steps

To solve this, we will follow these steps −

print 10*n and 9*n.

## Example

Let us see the following implementation to get better understanding −

#include<bits/stdc++.h>
using namespace std;
void solve(int n){
cout<<10*n<<", "<<9*n;
}
int main(){
int n = 512;
solve(n);
}

## Input

512

## Output

5120, 4608
