What's your problem exactly?
Cause you can run your program

[djkalai]

the problem is this,, we need to go class by class but the program cannot append


This question needs you to use a structure to store the information about a student detail. Your task in this question is to read information about students from the keyboard (maximum 50 students) and store in the input file and write out the output to an output file. The program will ensure that ONLY data written out satisfies all the requirements. The following are the attributes of a student:

• Name: a string with only alphabetic characters no longer than 30 characters. The first character from each word must be changed to uppercase letters.
• Course: a string with 2 characters only and must be changed to uppercase letters.
• Sex: a character M (male) and F (female) only and must be changed to uppercase letters.
• ID Number: a string that consist of 10 characters, with digits in positions 1, 2, 6, 7, 8, 9, and 10; and the alphabets in positions 3, 4 and 5. The alphabets must be changed to uppercase letters.
• Age: an integer. You may assume this field will always be an integer, but the age must be a positive integer and not more than 55.

You program must prompt the user for an input file name and an output file name. When reading from the input file, check each field for validity. If the data on a line is valid, you should add the student to the array. Make sure that you report any errors of formatting, and ignore the student record in question. Also, no two students can have the same ID number. So, before a student is added, make sure that there is no student with the same ID number in the collection already. Such an error should also be reported. Your program should report the total number of records read and the total number of invalid records found. The valid data must be sorted in ascending order and written the result to the output file. (Note: if a record has multiple errors, only one has to be reported.)

A sample of input shown below:
Sofea amani Ahmad 3e f 09ueb11111 23
Tan kok Lim EC M 09ueb11112 22
Priya A/P Muthusamy 3E f 09ueb11112 22
Kathy Anderson 3E f 09ueb11113 20
Karim Maarof ec m 09ueb11114 56
Chan Lai Mei ec f 0ueb11234 19
Ang Choon Kit 3e m 9ueb11235 20
Fatimah Abdullah ec f 09ueb11115 21
Chan Ah Kow ec m 09ueb11114 22
A sample of output to the screen:
STUDENT RECORD PROGRAM
Enter input file name: studentIn.dat
Enter output file name: studentOut.dat,
Ignoring Record Number 3 – duplicate ID number
Ignoring Record Number 5 – bad age
Ignoring Record Number 6 – bad ID number
Ignoring Record Number 7 – bad ID number
Ignoring Record Number 9 – duplicate ID number
Processed 9 student records
5 invalid records were found
Written output to student output file

A sample of the output file for the above data is shown below:
Fatimah Abdullah EC F 09UEB11115 21
Kathy Anderson 3E F 09UEB11113 20
Sofea Amani Ahmad 3E F 09UEB11111 23
Tan Kok Lim EC M 09UEB11112 22

Well, I am not able to complete the requirements of the question. I can input the data correctly but when i try to go through the check_name, check_course etc. function with my own data, it goes through a runtime bug.

[djkalai]

anyone here?

[z05DSL3A]

First edit your first post, at the start of your code type [code] and at the end type[/code]. Please do not post the entire code again.

Second, you will need to give more information about the error you are having, "it goes through a runtime bug" is not very help full.


The following may be helpful in asking you questions:

The question is up there .....

Okay, you still have not said what your error is, but I think you need to re-read your requirements because you program is far from doing what is asked for.
