Graphical Calculator with functions "Addition, Subtraction, Multiplication, Division, Mode, Factorial, Square, Power n, Sum of 1 to n numbers, Percentage" in c programming language

Introduction:-
In this post a special calculator with graphics which performs the following functions“Addition, Subtraction, Multiplication, Division, Mode, Factorial, Square, Power n, Sum of 1 to n numbers, Percentage”in c programming language. In this program I use the graphics in C programming language. By using this program you can perform the all the major functions which is needed to calculateHow to run:-
To run this program at first make a *.c file and write this code in *.c file and then run with Turbo C or other C programming compiler.
