step 1:
download files:
https://drive.google.com/file/d/1ULN_XcrbDkls2U2DlYkNM_yiua5h-_NI/view?pli=1
step 2:
Copy libbgi.a to the lib folder of Dev C++. The default location is C:\Program Files (x86)\Dev-Cpp\MinGW64\lib.
step 3:
Copy graphics.h and winbgim.h to the include folder of Dev C++. The default location is C:\Program Files (x86)\Dev-Cpp\MinGW64\include.
step4 :
Open Dev C++ and go to Tools -> Compiler Options. Select the Parameters tab and check the box for “Add the following commands when calling the linker”.
In the linker text area, paste the following commands:
-lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32
. These are the required linkers for graphics.h file.
step 5:
#include<graphics.h>
#include<conio.h>
#include<stdio.h>
int main()
{
int gd = DETECT ,gm, i;
float x, y,dx,dy,steps;
int x0, x1, y0, y1;
initgraph(&gd, &gm, "C:\\TC\\BGI");
setbkcolor(WHITE);
x0 = 100 , y0 = 200, x1 = 500, y1 = 300;
dx = (float)(x1 - x0);
dy = (float)(y1 - y0);
if(dx>=dy)
{
steps = dx;
}
else
{
steps = dy;
}
dx = dx/steps;
dy = dy/steps;
x = x0;
y = y0;
i = 1;
while(i<= steps)
{
putpixel(x, y, RED);
x += dx;
y += dy;
i=i+1;
}
getch();
closegraph();
}
