hi! i need help with my code...i dont have any syntax errorrs but when i run it it doensnt run!! i dont kno what to do!! plss i really need help!!!
i have to write code tht uses array to store student information and calculate the average, letter grade. i also need help sorting the student name in alphabetical order, deleting a student and editing a student's info! (i basically need to everything thts in my menu)

please i am really desperate!! i really need help!! thanks in advence times a million :D!

Please use code tags.

[code=cplusplus] // paste code here

[/code]

Your question is also too vague for this much code. What specific problem are you having ("It doesn't run" is too vague)?

Please provide the smallest possible segment of code that isn't working, along with example input and actual output vs expected output.

Of course, the original post is extremely ill-formed.
However at least one defect arrests attention: sort_names function is wrong. Sorting loop index is out of range: names[j+1] refers to inexisting string element when j == size-1.

To OP: don't try to start this code as is: there are too many other defects in this program now. Debug it step by step. For example, take sort_name function, write a simple test case and try to debug it then take another function (Menu, read_... etc). Don't force to play a team of cripples.

hi! i need help with my code...i dont have any syntax errorrs but when i run it it doensnt run!! i dont kno what to do!! plss i really need help!!!
i have to write code tht uses array to store student information and calculate the average, letter grade. i also need help sorting the student name in alphabetical order, deleting a student and editing a student's info! (i basically need to everything thts in my menu)
sample input is Toots Sweet

87 76 90 100
sample output: Tests

Name 1 2 3 4 Average Letter Grade

Toots Sweet 87 76 90 100 92.33 A
to be specific my problem is that everytime i run the program it does the menu but when i press the options it doesnt do them...and i need help writing a sorting names function, i dunno how to do tht!

please i am really desperate!! i really need help!! thanks in advence times a million :D!              
// paste code here

also sorry i am new here i didnt how things work but thenks guy i appreciate any help! :D

You have a problem with the whole program or just a part of it ? Because its really hard to scan through every part...

To the OP:

  1. > // paste code here
    We aren't going to post free code for you, however we can help you to accomplish the more tricky parts, give us a thorough problem description (not just: My program doesn't work, can you fix it for me?)
  2. We're not code rescue rangers or something, before developing any more programs, you should definitely consider taking a look at this *excellent* page first!
    (If you'd followed the process described there, you wouldn't have run into any problems :))
  3. Prevent the thread from becoming cluttered up by not every time reposting your whole code, just mention where you've changed your code or attach your code (as an attachment) to this thread, in that case the thread will be much easier to read...
