Thread: Code will not compile - code from a book!

First, just a convenience detail. Use code tags (read announcement at top of forum).

Anyway, what you have there is a { where there should be a }. And, 'void main' is bad. Use 'int main'. A search on this board will reveal a dozen answers as to why this is so. As a result, you will also want a 'return 0;' after your print. And... Your window will probably disappear too quickly to see anything. Check this site's FAQ for information to prevent this.

Cheers.

Ok, I appreciate the help.

Oh, and sorry for not using code tags, I will use them next time.

Once I read about how to use 'em I will edit my original post and add code-tags for the code example!

Third, its indentation is bad for newbies. Fourth, it's got a typo - the last bracket should be a CLOSING bracket, not another opening one. And last, it uses printf() instead of cout.

Here's a fixed up version of the program:

Code:

#include <iostream>
 
int main()
{
   //Write "Can you C++ now?" and then go to the next line
   std::cout << "Can you C++ now?" << std::endl;
 
   //Pause the program so it doesn't close right away
   char c;
   std::cin.get(c);
  
   //Quit the program
   return 0;
}

WOAH, MAN I AM READY TO BURNNN THAT BOOK!

Oh well, looks like I'm gonna have to find another book that is actually worth a crap.

Thanks for the help, though! I intend to stay here for a while.

Ok, Now i'm REALLY confused! :P

First of all, your code uses std::cout and many other different things than the tutorials on this website (cprogramming.com , of course) do.

For example, on their first tutorial, instead of placing std::cout and all of that other stuff, this is what it looks like:

Code:

#include <iostream.h> 
int main() 
{
  cout<<"HEY, you, I'm alive!  Oh, and Hello World!"; 
  return 0;    
}

Of course, you must add "cin.get();" before the "return 0;" to get it to show up without closing, at least I did. :P

Anyways, what is going on! SO many different ways of doing things - i'm confused out the yin-yang!

As to the FAQ I trully believe it needs to be updated, just keep coding and experimenting and coming back to the board, that's what it's hear for.

Ah, awesome links!

I'm about to check out that "Bruce Ecekl's Thinking in C++ 2" here in a few minutes, so hopefully that will give me some help.

Thanks for the support guys! It really means alot to me!

Another awesome book that will introduce you to ideas C++ and then explain it well is "C++ How To Program" by the Deitels. I got a copy on either Ebay or Amazon.com for less than $10.

Hmm... Hunter's answer is more complete... That's all you'll need to run the program. It'd be worthwhile to look into cin and such so that you know what he is doing and why.

Cheers.

Do a search for books on this forum too. It has been discussed at length, and additionally, the name of a site with reviews of many programming books has been posted.

Ah, thanks for being so kind and helpful guys.

I will check out those things that you told me and see if I can learn anything from that.

Oh well, wish me luck!!!
