Here is a simple program that I wrote using C++ that will compute and evaluate the grades of the students using two dimensional array in C++ as our data structure. I hope you will find my work useful I am using Dev C++ as my C++ compiler and CodeBlocks as my C++ text editor in writing this program. Thank you.
