Description:
(A1) Enter student data from keyboard and write to file.
(A2) Read student data from this file into a group of parallel arrays (or a struc array) and display the array contents.
(B) Repeatedly prompt for a student name, search for and display the student&'s data (if found).
I will send the files needed to complete this project.
Deliverables:
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Complete ownership and distribution copyrights to all work purchased.
(A1) Modify program readtofile.c to load the following arrays from the keyboard. After loading, display the array contents. Student Arrays (all of size STUDMAX=10). Reject any entries that do not meet the requirements below.
a. stud_id[ ] = array of student id&'s exactly 6 char in length
b. stud_last[ ] = array of student last names (15 char max)
c. stud_first[ ] = array of student first names (15 char max)
d. stud_gpa[ ] = array of gpa values validated to be in range 0.0 - 4.0
(A2) Modify program readfrfile.c to load the above arrays from the file. After loading, display the array contents.
(B) Add a search function to program readfrfile.c. This function, in a loop, prompts the user for a student name (last, first), searches for and displays the student&'s data (if found). If the name is not found, display a “not found” message.
Hints:
1. For a 15 char max stringsize, you must define the string as having at least 16 chars to allow for the null string terminator.
2. The columns in the student data display should be user friendly and line up.
3. Be sure to show all the invalid cases in your tests, including student found, not found. Also two students with same last name.
