Draw a Circle With Asterisk in C
The code beneath is a unproblematic style of drawing a circle without using fancy functions to spring 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,2)+pow(y,2)); } int principal ( ) { int c=0; int r=10; const int width=r; const int length=r*1.5; for (int y=width;y >= -width;y-=2) { for (int x=-length;x <= length;x++) { if ((int) pth(x,y)==r) cout << "*"; else cout << " "; } cout << "\northward"; } cin.get(); return 0; } If you desire more than advanced lawmaking and y'all are on the windows platform and y'all use Visual Studio to create programs then the code below would exist of intrest.
It uses functions like SetConsoleCursorPosition() to ready ten and y positions, SetConsoleTextAttribute() to set colors. The code draws lines , pixels, rectangles and circles in the panel text window.
