Assignment 1

PI Calculation

Code

  1. include <cstdlib>
  2. include <iostream>
  3. include <iomanip>
  4. include <math.h>

using namespace std;

int main(int argc, char* argv[]) { if(argc < 2) { cout<<"Please input the number of circle points"<<endl; }

int npoints = atoi(argv[1]); int circle_count = 0;

srand(time(NULL));

double xValue, yValue; for(int i = 0; i < npoints; i++) { //Generate random numbers xValue = (double) rand()/RAND_MAX; yValue = (double) rand()/RAND_MAX;
