Subject Grade Solver in C++

In this article will show you how to write a program using C++ that will ask the user to give the subject of the student, the prelim, midterm, semifinal, and final grade and then the program will compute the general average grade of the student and display the results on the screen.

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.
