[SOLVED] How to get high frame rate while using putpixel() in C?

How to get high frame rate while using putpixel() in C?

I was working with a code to print pixels.

// C code

#include <graphics.h>
#include <conio.h>

int main()
{
    int gd = DETECT, gm;

     initgraph(&gd, &gm, "C:\\TC\\BGI");

     for (int i = 0; i < 100; i++)
     {
         for(j = 0; j < 200; j++)
         {
             putpixel(i, j, GREEN);
         }
     }

     getch();
     closegraph();
     return 0;
}

Is there any way of achieving faster response from C compiler while using putpixel() in this code? The speed with which console gets colored with the execution of putpixel() is pretty slow, so I was wondering if there was any other library which I could use to speed up the printing pixel process on the screen using C on a windows system or a Linux one?

Solution

putpixel() is pretty slow, no matter which framework or library you use. Try to create a bitmap and calculate the memory address of each pixel yourself.

Cross-platform frameworks that allow you to do such a thing are SDL and Allegro.
