Student Record System in C
Simple functions have been to manipulate data structure and file handling, so here I will just list the features of this project.
· Add student record
· Search student record
· Modify student record
· Generate marksheet
· Delete student record
· Change password
The functions listed below have been used to produce background with color effects. They are described in the source code with comments.
· void SetColor(int ForgC)
· void ClearConsoleToColors(int ForgC, int BackC)
· void SetColorAndBackground(int ForgC, int BackC
