Data Structures

[Salchester]

Hello,

What data structures are there, and what are they for.

for example: Int, Char etc

Better buy a book or search for an online tutorial. These are the very basics. Learning from scratch from a forum is far from efficient I'm affraid.

I'm not a beginner, i have used and programmed in C++ many times, only now i need to decide whether to use arrays etc. But, can't decide unless i know what they are, and how they work.

you contradict yourself.

Didn't we have a conversation about this in another thread... Can't remember which, but the function sizeof() will be valuable to you, if it's structure-size you're concerned about.
Basicaly any type you create your variable as, can hold info on anyother type, but the size on a specific type prevents it from beeing usefull in comparison to the type intented to be used.

As for usage, it's kinda selv-documenting...
char, oh what do you know, it holds a single char or an int value from 0 - 255, given that it's 8 bit (or a byte if you want to count it that way)
int, oooh... let me guess, please let me, me, me, me..... I guess it would hold an integer... Yay what do I win....
double/float, is for fraction or floating values as it is known in the computer world.
Then theres ofcause all the further extension on the byte-size of the type, with long, unsigned, short.

But if you get any teaching book, I guarentee you it will hold a table with every type, its size, and what it's for.

I think he means composite structures like linked list or multi dimensional arrays.

In that case, he should find an online toturial on vector, list, map, stack and so on.
One wants to find out what datastructure fits the problem domain. The concrete code is the final part (testing not included, duh).
Find out about STL guys.
