Addition and Subtraction Using Function in C++

 I wrote this program to ask the user to give two numbers and then the program will compute the sum and difference of the two numbers using functions in C++ programming language.

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.
