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


Input − N=3

Output − Pieces of circle: 6


Approach used in the below program is as follows

  • We take N for a number of cuts.

  • Take pieces=1*N.

  • Print the result..


#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;


If we run the above code it will generate the following output −

Number of pieces of circle: 4
