Most of the students in Windows use graphics.h header file in there programs that are written in TurboC. This is a reason that some don’t wanna migrate to Linux well there is a solution for that to. Just follow the steps that i did in Ubuntu..

First run sudo apt-get build-essential to install necessary compiler tools.

Then, install the following packages:
libsdl-image1.2
libsdl-image1.2-dev
guile-1.8
guile-1.8-dev
libsdl1.2debian-arts
libartsc0-dev
libaudiofile-dev
libesd0-dev
libdirectfb-dev
libdirectfb-extra
libfreetype6-dev
libxext-dev
x11proto-xext-dev
libfreetype6(upgrade)
libaa1
libaa1-dev
libslang2-dev
libasound2
libasound-dev

You can install them via Synaptic Package Manager (System/Administration/) one by one. or type the following command in the terminal :
sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-1.8 guile-1.8-dev libsdl1.2debian-arts libartsc0-dev libaudiofile-dev libesd0-dev libdirectfb-dev libdirectfb-extra libfreetype6-dev libxext-dev x11proto-xext-dev libfreetype6(upgrade) libaa1 libaa1-dev libslang2-dev libasound2 libasound-dev

After this download libgraph-1.0.1 (This is the link) to your Home Folder.
Right click on it and press “Extract here”
Now type in the terminal
./configure
sudo make
sudo make install

This completes the installation.

Now just add the following lines in your program:
int gd,gm=VGAMAX; gd=DETECT;
initgraph(&gd,&gm,NULL);

and compile using g++ like:
g++ test.cpp -o test.o -lgraph
And execute the program by ./test.o

If on compile it gives u an error that says “could not load shared libraries” or something like that just run the following command and it should fix it
sudo cp /usr/local/lib/libgraph.* /usr/lib

An example program(to print a rectangle) :
#include
#include

int main(void)
{
int gd=DETECT, gm=VGAMAX;
initgraph(&gd, &gm, 0);
moveto(0, 0);
rectangle(50,50,500,200);
while (!kbhit());
closegraph();
return 0;
}

If there are any problems please leave a comment.
