Thread: Simple C++ question

I'm in my first class for C++. Can someone please tell me how to declare a string "consumer"?


Thanks in advance

If I were to have #include main() can I also have #include <string> in the same code?

Thanks for your response.

you're not supposed to #include main().

anyways, yes, you can include more than one header file, and if your program calls for more then one, than you should.

I'm confused! Can you please explain to me why I'm not supposed to use #include main()? Because, this is what my professor is teaching us.

#include main() won't even compile, I don't know how you can be taught such abominations anyway. If it is your first class, I won't be a good teacher, so, I'll just let others explain why it is so.
But this post will be aimless if I didn't do something for you, so, here is a basic explanation.

Code:

// Consider a simple program that does nothing.
// Here's the code.

int main()
{
    return 0;
}

For now, you don't need to know what int main() is, all you have to keep in mind is that everything inside of the brackets is your code and will be executed.
See? there's no #include main() thing. #include is designed to include a file into the one which use the directive. For instance, if your file, named "main.cpp" uses #include <stdio.h>, the file named "stdio.h" will be copied into the "main.cpp" when it is loaded into memory to be compiled.
The content of the file is not of import to you right now, just understand that it is here for you to use functions and classes (don't worry if you don't know what it is at present) that weren't available otherwise.

OMG..I'm sorry guys! I'm the ignoramus! lol..

Lack of sleep is a mofo. LMAO

I hope my post here isn't a reflection of what my grade is going to be in this class.

#include <iostream.h>
#include <string>

int main()

Jeez I'm a goof! Ok so a revised question here.. You can use as many #include as you see fit..correct?

Yes

Umm... Not realy... Header files are there for a purpose. Such as std, a standered namespace, won't work without iostream. Putting to many will just increase file size and make you look noobish...

Why? If you need 10 functions from 10 different headers, you have little choice but to include all of those headers. Not doing so would give unpredictable behavior and make you look noobish.

Oh, I thought he ment just put them there for like no reason, my bad

I still use .h.

Only because when I use

Code:

using namespace std;

It says there is no namespace std.

O_o

get a newer compiler.
