How can I draw a circle by * in c++ ?

Answer 1

#include<iostream>
using namespace std;
int main()
{
float r;
cout<< " Enter the Radius"; cin>> r;

float pr = 2; // pr is the aspected pixel ratio which is almost equal to 2

for (int i = -r; i <= r; i++) // loop for horizontal movement
{
for (int j = -r; j <= r; j++) // loop for vertical movement
{
float d = ((i*pr)/r)*((i*pr)/r) + (j/r)*(j/r); //multiplying the i variable with pr to equalize pixel-width with the height
if (d >0.95 && d<1.08) // approximation
cout << "*";

else cout << " ";
}
cout << endl;
}
}
