Programming

You must have put it in wrong because it compiles fine for me (I copied and pasted from my post).

I edited my post. It works now. It didn't because I had it in a Windows App instead of Command Prompt program. That tends to crimp the system a little.

I sugget using "system("PAUSE");" for console aplications. You'd need to add the following line at the bigining:
#include <stdlib.h>

Okay well now you're set and can basically learn all of the standard C++!

I wouldn't do that because it depends on your OS and it really isn't standard... It also writes extra stuff at the end of the program and you may not want that. However other cin commands in your file can cause problems so if you use cin at all, put this code before the cin.get();

cin.ignore();

Windows/DOS is pretty standard, if you ask me. A windows based compiler will not make programs that run on other operating systems anyway. So unless you plan to compile your program for different operating systems, system("pause") should work just fine.

True that system("pause") does give a pause message. I do not think this is detrimental for a beginner's consol program.

And of course it should be noted that "pause" is a DOS command, not a C++ command.

Another function you could use is getch(), which is found in casio.h I believe. This will also only work on windows. This is also usefull for actually getting input from the player without using stdin.

Um... Okay... what is cin.ignore? Why does cin cause problems?

 

[Speedo]

To be honest, C++ makes little sense to me. It seems to be based on creating command prompt programs, and that doesn't hold well on my supa-system.

Look at the Win32 API then (at least for windows programming).

The easiest way to get the programs to stay on the screen is to run them from the command prompt (Start>Run and enter cmd). Personally I prefer to compile and run from the command prompt.

You'll have to learn more of the language. I can't explain easily if you don't know much of the language yet.

I feel like so normal and ungeeky now.

.... until you master big programming word: Pointers, you won't be considered as programmer nor you know C++.

Learning C++ syntax takes a week; learning how to use pointers properly takes years.

Also it seems that you don't have formal related mathematical knowledge- that is part that "real" programmer are made of.

 

[Padma]

Yeah, you're not a real geek until you can discuss the pros and cons of using pointers; why C/C++ uses them, and why java (for instance) does not.

I hope this isn't directed at me...

to anybody who wants to be a decent programmer.

I thought Java automatically uses pointers without you specifying

Each time I try to learn C++ I get stuck at pointers

Then I have one sentence to help you my friend. Are you ready? I'm only gonna say this once. *clears throat*

A pointer is a type of variable that holds a memory address.

This one sentence made the little light bulb click on in my head whenever I was stuck at pointers (a while back).

 

[Souron]

You can have function pointers too. Those don't point to memmory.

But that's really the exeption.

Yeah but I can guarantee he's having trouble with the pointer variables...

 

[Comraddict]

ok homeyg, what is the variable type of the pointer? i.e. string, int, etc.
