Count pieces of the circle after N cuts in C++

We are given an integer N which represents the number of cuts applied on a 2D-circle. Each circle divides the circle in two halves. Goal is to find the pieces of the circle after N cuts.

Number of pieces= 2 * no. of cuts

Let’s understand with examples.

Input − N=1

Output − Pieces of circle: 2

Explanation −

Input − N=3

Output − Pieces of circle: 6

Explanation −

Approach used in the below program is as follows

We take N for a number of cuts.
Take pieces=1*N.
Print the result..

Example

#include <bits/stdc++.h>
using namespace std;
int main(){
   int N=2;
   Int pieces=2*N;
   cout <<endl<<”Number of pieces of circle: ”<<pieces;
   return 0;
}
