Mini project Employee record system using C

The employee record system is very simple and for very beginner mini project. It is based one the menu-driven program for elementary database management. It employs all the basic technique of file handling in C. It consists of following features
  • Writing the data in binary file
  • Reading the data from binary file
  • Modify the record
  • Delete the record

This project is a learning milestone for a beginner who wants to step into the database management project in C. The code is also available on GitHub.

Here are List of Mini projects in C

    we need to download "windows.h" for code support

    please provide us the same.

  2. I think you tried it on Turbo C which doesn't support windows.h. Best way is to use Code::Blocks IDE having GCC compiler

    sir,
    i have some very simple programming doubt in two dimensional character arrays

    here is the program

    # include
    #include
    # include
    void main()
    {
    int i=0;
    char name[3][10];
    printf("n enter the names n");
    for(i=0;i<3;i++)
    {
    scanf("%s",name[i]);
    }

    printf("you entered these namesn");
    for(i=0;i<3;i++)
    {
    printf("%sn",name[i]);
    }
    getch();

    }

    in this program i would like to chk for null character using for statement..how do i do that

    why because suppose..if the size of array is 3X5

    and if I enter any name which is more that 5 characters..I get an error null point termination..

    should I use 2 loops to enter the names and chk for null character

    or with single loop how should I chk
