Hi,
Nice to hear that you are good at basics, coming to advance concepts, you need to first clear with concept and you need to visualize the picture how program is going to flow. As you get clear concept visulization then your hands will go through the program code. I'm sure you are puzzled while implementing program.

I would say spend some time with "C" progamming forums, then you will get hands on confidence and you won't get stuck any more.

Hope it helps.

Hi,

1. Every much possible
2. sparse matrix - conveys number of elements in matrix is zero
3. In order to convert from sparse to ordinary matrix -- you need to decide, what would be matrix size after conversion.
4. Second, what would be you would like to replace value instead of zeros.
5. If you decide on above two constraints, then matrix is basic either you can do through arrays or structure (pointer) linked list.

Hope it helps.

Think simple, you can achieve it.

Before answering your query, just think below question

1. Why would any provide free assignments for any one ?

Now, how to make your assignments / knowledge stronger , as day follow, you need to register yourself to some "C" programming "forums". This is starting point from where you knowledge expands and you grow stronger at your conceptual and practicals. Try to resolve queries posted by different end users (since those are different issues and assignments), as you solve you are going to master "C" programming. As you spend your time you will get your results.

Hope it helps
