Basic Calculator Program in C++

A simple calculator program that I wrote using C++ as my programming language that can perform basic arithmetic operations like addition, subtraction, multiplication and division.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me in the following email address for further details.  If you want to advertise on my website kindly contact me also in my email address also. Thank you.
