Hoow to Draw Circle of Stars Python
The lawmaking below is a simple way of drawing a circle without using fancy functions to jump to any arbitrary chosen x or y position.
#include <iostream> #include <math.h> using namespace std; int pth (int x,int y) { return sqrt (pow(ten,ii)+prisoner of war(y,2)); } int primary ( ) { int c=0; int r=10; const int width=r; const int length=r*1.five; for (int y=width;y >= -width;y-=two) { for (int x=-length;10 <= length;x++) { if ((int) pth(10,y)==r) cout << "*"; else cout << " "; } cout << "\due north"; } cin.go(); return 0; } If you want more than advanced code and y'all are on the windows platform and you use Visual Studio to create programs then the lawmaking beneath would be of intrest.
Information technology uses functions like SetConsoleCursorPosition() to prepare x and y positions, SetConsoleTextAttribute() to set colors. The code draws lines , pixels, rectangles and circles in the console text window.
