Header Symbol

[ChroniX]

Hello, I recently took up learning C++ in preparation for future game development (And sure do have plenty of time to learn since I don't attend school or have a job). I ran into something I'm not sure of that I am hoping somebody here could answer for me.

Does the # symbol in the header for "#include" stand as a sharp or a number? I assume sharp at the moment, but will revoke my thoughts until I get a correct answer.

Thanks,

it's a precompiled header or directive.  tells the compiler to do something before compiling the code.  in this case, including a file full of probably definitions

they're called preprocessor directives, here's a quality hyper link: http://www.cplusplus.com/doc/tutorial/preprocessor.html

I might be a little off, but I think what you are asking is if the symbols used in C++ (like #, *, ->, ect.) have any ties to what the symbols would mean  if you were not using a programming langauge... I think.

The answer to that would be no. The '#' is just a non-alphanumeric symbol that happens to be used in pre-compiler directives. Some math symbols (+, -, ect) are common sense, adding by using the tilde would be confusing.

I think thats what you were asking... I'm not sure though...

Sounds right on target to me! 

I just never knew as to whether or not the symbol had any sort of name associated with it.

C++ is a great language to learn. I'm sure my time spent learning it will be well worth it. I know that Battle.net's population is slowly coming to an end, but I want to eventually write a bot for channel moderation.

Also, I have heard you can only use the cout function when using <iostream>. Is this true?

[DeTaiLs]

Yes it is true, read this it tells you some of the functions for each libary

cout isn't actually a function, it's an object.

Well Mynd, thank you very much for pointing that out.

Well I'm having a problem here and hopefully somebody can help me. I get this error when trying to compile the code below

error C2784: 'std::basic_istream<_Elem,_Traits> & (Location of project on drive)

Code Select Expand

#include <iostream>

using namespace std;

int main()
{
int number;

cout<<"Please enter a number: ";
cout>> number;
cin.ignore();
cout<<"You entered: "<< number <<"\n";
cin.get();
}

cout >> numer;


you can't get input from cout.

Code Select Expand


cin >> number;

Ah okay, that's it! Thank you very much for your help.

What is wrong with this code? It will compile but wont execute.

Code Select Expand

#include <iostream>

using namespace std;

void playgame();
void loadgame();
void playmultiplayer();

int main()
{
  int input;
 
  cout<<"1. Play game\n";
  cout<<"2. Load game\n";
  cout<<"3. Play multiplayer\n";
  cout<<"4. Exit\n";
  cout<<"Selection: ";
  cin>> input;
  switch ( input ) {
  case 1:
    playgame();
    break;
  case 2:
    loadgame();
    break;
  case 3:
    playmultiplayer();
    break;
  case 4:
    cout<<"Thank you for playing!\n";
    break;
  default:
    cout<<"Error, bad input, quitting\n";
    break;
  }
  cin.get();
}

Why don't you use a little debugging (either with breakpoints in VS or simply by printing out the value of input)
