This graphical scientific calculator purely written in C programming language. It uses small functions to draw buttons on the screen and perform scientific operations like conversion, logrithm, and other operations. Every operation can be performed using the mouse buttons as well as keyboard. It can perform almost all the functions shown on the screen except few functins which will be implemented in the next version of this calculator code.

Before compilation make sure you change the line 460 ( initgraph(&gdriver, &gmode, “f:\\tc\\bgi”);) to show the actual path of the graphics library on your machine i.e. bgi folder of your turbo C/C++ compiler installation.
