Carla, you will need to begin by defining a maximum number of students you are dealing with (unless you want to use a linked-list). #define MAXS 200.

C Structures with examples - Learn C programming language covering basic C, data types, functions arrays, pointers, C Structure with examples etc. Hillsong Aftermath Album. C Program to Sort the Record of Student. This is c program that ask user to sort student data. Write a Program to Create a Structure of N Students using.

The you define your struct. Codegear Rad Studio 2009 Keygen. In main() you will allocate 200 pointers to your struct with calloc not malloc so you explicitly set the pointers to NULL.

Then as you read each set of data from the file, you can allocate a struct with malloc and fill in the data. Since you are using pointers, use the arrow notation to access struct members (e.g. Student->name) instead of the. You can travers all structs while *ptr!= NULL – Sep 11 '14 at 2:04 •. That just means if you don't give the program a file name as an argument on the command line, it won't run and exits telling you to give it a 'filename please' - the csv is just a reminder that it wants a comma separated values file.

It's just a way of checking that the program has been given the required input. You could make the program ask for a filename, but that just makes the code longer. Easiest just to pass what you need on the command-line. So run it with./programname input_filename.

See the output: section for an example. – Sep 11 '14 at 5:25 •.

@CarlaRamirez There are many good core C principals involved in this project you are doing. Take the time to understand what each line of code does AND why it does it. Your project is exceptionally good at forcing you to think 'How am I going to tie all these structs together in a useable way?'

That applies to collections of any type of data structure. The dynamic allocation and pointer use is another good learning opportunity. Medieval Castle Siege Games. Don't shortcut the analysis (even though it is tempting).

Ask again, when you get stuck. – Sep 11 '14 at 5:31 •. @CarlaRamirez: I have added a new section to the bottom of the answer that will read the data in the format you provided. As others and I have said, when you declare students with as student *students instead of student **students, you make it nearly impossible to tie the stucts together in a way that will let you pass all students to a function or iterate over all students in your program. You can do it your way, but you will need to keep global variables for count and the sums of the age and gpa in order to calculate the average at the end. – Sep 11 '14 at 6:20.

Sarfaraj Alam aka Sam is amazing with any kind of programming assignments. You name any language C, C++, JAVA, Matlab, C#, Web Application, Database, Data Structure, Game, Animation, etc. As mentioned I did all my assignments throughout my semester and I got more than 98 or more which is an A in every assignments I gave to Mr. Sam, He helped me in all the assignments.

I used many online services for my assignments before but they were rude and no clarity on how the work will be done, no real customer service or no real communication until I found out about Sam. I called him the very first time and asked his functionality and how he works completing an assignment, I was never satisfied as I am right now, I am still using his services for my Projects, assignments, etc. I felt I am talking to my friend and we bond a relationship into a real good friendship. I would give my assignments a day before and he would anyhow do it without any hesitations and I would still get full score on my Projects and Assignments. I am actually a very busy person working and going to school is really stressful, but when Sam is there you can sleep very peacefully, with no tension. He is very friendly and would understand your needs, urgency and quality of the work as per your needs.

I read through the testimonials and people were complaining about the prices he charges, I would say if you need to get your work done in just one day who would want to do it? No one but Sam, and the quality is 100%. In my opinion I would highly recommend his services, please talk to him and he will get through your assignments as with full attention and error free. I was troubled a student having hard time in my career but using his services I am close to getting my degree almost. Thank you so much Sam, I highly appreciate your services to me. Studying Information technology became a huge headache,but things became quite simple and interesting with the help from Sarfaraj. His brilliant work left no scope for mistakes and things became quite simpler after that.
