What are vectors?

[krnekhelesh]

I read that vectors and arrays are almost the same. Could you explain this to me?

ok they are resizable array! That's good, I mean instead of just creating a big array and wasting memory we can use vectors.

Can we drop the .h from all the C++ headers? But it works for me even though I use them.

[Killer_Typo]

vectors are much like arrays

#include <vector>
int main()
{
//standard way to create an array
int myarray[someconstsize] = { 0 }; //assigns all values to default zero
 
//vector declaration
vector<int> myvec;//declares an int type vector
 
//adding data to them
 
myarray[0] = 4;
 
myvec.push_back(4); //adds four to the end

this is in no ways the end all be all deffination, but a somewhat decent look at em :)

I'm not even sure you can use stl stuff in turbo c. (old one that it).

When you finish your edjumacation and if you want to learn proper c++, get dev-cpp from bloodshed.

[krnekhelesh]

I have dev-c++ but I didn't use it because it didn't support graphics

could always work with Visual Studio

i happen to find this environment quite fun and easy to work in.

Dev is better for pure c++, VS tends to convolute what is standard c++. Such as when killer typo mistook

for each

As standard c++.

heh it's actually because of a setting in VS which can be turned off to disable ;)

dont try and set the standard with my mistake that would be a mistake in itself :)

i've asked a couple professionals (30+ years experience in software/hardware..etc development, one of which is currently head of product research development) and when i asked about the compiler they use, they replied that they use microsofts products.

when i asked about other compilers, like borland, turbo, bloodshed they just laughed them off.

[iamthwee]

Nah, VS is too bloated and c++.net is horrible.

For pure c++. i.e no windows GUI crap, you don't need Visual Studio.

And anyway, if you are writing code it is best to test it with different compilers and operating systems to ensure portability.

[krnekhelesh]

ok what are you two arguing for. I have neither VC++ nor Bloodshed. BORLAND C++ is the best!!

hehehe i think you win :)

look up the sexually transmitted library (STL)

and the namspace std

along with vectors

very good read and you will learn much in doing so.

the standard template library introduces a lot of functionality. http://www.sgi.com/tech/stl/stl_introduction.html

> BORLAND C++ is the best!!
'Created a game using C++ and OpenGL' is much better thing to write on your resume than 'Created a game using Borland C++'.

That's because you are in a school being taught by clowns. :D

You sure about that? Because you are arguing about compilers when the topic posted isWhat are vectors?

So whos being kiddish?

> You sure about that? Because you are arguing about compilers when the topic posted is What are vectors?

Borland, Visual studio and dev-cpp are not compilers.

:D

And the argument is relevant because a lot of the code you write in the crusty old turbo c will not support what is standard c++. That may include std::vectors.

:D

[krnekhelesh]

you can't even understand what I meant by compilers and besides since I am just learning vectors I wouldn't start of with std::vectors.

I mean I will just start with declaring vectors and accessing vector member that's it, and I am sure that turbo c++ would support that.

Who told you I am using turbo c++ ? I am using borland C++ 5.5. And for your information that is not old.

[krnekhelesh]

So you are telling that arguing about whether to use dev c++ or VC++ has got everything to do with the topic WHAT ARE VECTORS?

If they are to you then I think you don't understand English.

Did you read the replies you got at the beginning of the thread? Your question was answered there - If you need a more detailed explanation than the one you recieved, then you need to ask a more specific question

The compiler discussion has been brought about by the fact that your ancient old Turbo C++ compiler doesn't support many modern C++ language features, vectors likely being one of these features.

Never in this topic have I mentioned that I use Turbo C++. Please read the topic fully before posting!

Thank you
