A C++ program for a student records system

I need a C++ program to store a single students marks for 7 subjects. Each subject has its mark split as follows: un001 assign:50%, labs:20%, test:30% un002 assign1:25%, assign2:25%, assign3:50% un003 protfolio:40%, group work:60% un004 assign1:30%, assign2:30%, assign3:40% un005 assign1:30%, assign2:70% un006 project:50%, test:50% un007 group work:100% The program requires a base class for member functions to: -Enter marks for each subject. -Display a chosen unit marks & any marks still required in that unit to obtain a pass (40%). -Display all units with total marks to date & the average mark over all subjects. And an additional derived class to: -Save data into a file. -Read data from a file into the program. -Remove any particular mark and replace it with a new one. And all this to be kept as simple as possible throughout. Run in a simple dos box, nothing visual. I am also offering an extra $20 bonus if this project can be completed within 1 day. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. (with comments on functions of each part of program if poss). 2) Complete ownership and distribution copyrights to all work purchased. ## Platform windows xp dos box
