Student Record System In C
Introduction :-
Not at all like different smaller than expected ventures distributed in Code with C, this little task in C Student Record System has an extraordinary way of coding and is introduced in a beautiful way. It utilizes documents as information base to perform record taking care of tasks like add, search, change and erase records to deal with understudies' records. In this venture, you can likewise produce mark-sheet for understudies.
Here, a control center window is practically partitioned into 2 sections – one is static and it doesn't change, while the other is dynamic and it changes now and again. The content are coded utilizing different shading related capacities to make them static.
The source code for this scaled down project is sans mistake, however not complete. There are numerous spots for upgrades and improvements inside the undertaking. This C smaller than usual undertaking on understudy record the board framework is gathered in Code::Blocks IDE utilizing GCC compiler.
Features of Student Record System in C:-
Straightforward capacities have been to control information construction and record dealing with, so here I will simply list the highlights of this task.
Add understudy record
Search understudy record
Alter understudy record
Create marksheet (additionally see: understudy report card framework project in C++)
Erase understudy record
Change secret phrase
The capacities recorded underneath have been utilized to create foundation with shading impacts. They are portrayed in the source code with remarks.
void SetColor(int ForgC)
void ClearConsoleToColors(int ForgC, int BackC)
void SetColorAndBackground(int ForgC, int BackC
void gotoxy (int x, int y) – I have been portraying this capacity in the majority of the C tasks distributed on this site. You need to comprehend this capacity as it's anything but a significant one utilized in this smaller than usual task on understudy record the executives framework.
This capacity permits you to print text in any spot of screen. Utilizing this capacity in Code::Blocks requires coding, yet it very well may be straightforwardly utilized in Turbo C. Here is a code for this capacity in Code::Blocks.
Code :-
