HELP WHIT-What is your name? Hallo _____

Ok im a begginer(started yesterday)and I have been working whit the variable int

I want to do a program that asks for your name and then greets you.I have this-

Code:

---

#include <iostream.h>
#include <stdio.h>
int main(int nNumberofArgs, char* pzArgs[])
{
    string name;
        cout << "What is your name?";
        cin >> name;
        cout << "hallo,";
        cout << name;
    return 0;
}

---

But it doesent work
When I work whit the variable int and put it in My code(Im using MicrosoftVisual6.0) "int" turns blue but when I put "string it doesent turn blue=\

WHATS WRONG ? ? ? ?

Thanks in advance

Borrow a good C++ book from your local library.
Perhaps reading the FAQ also helps.

If not, include <string> to your sourcefile, and add the line "using namespace std;" somewhere.

I can't figure out what you're trying to do with this:

int main(nNumberofArgs, char* pzArgs[])


Just make it

int main()


It also wouldn't hurt to read this.

First, get rid of the "arguments" in 'int main()'. They're unnecessary here.

Second, 'string' is not a "member" of <iostream> but rather of <string>.

Third, your question sounds "panicky". Read the FAQ. Panicky questions don't play well on the Board.

Fourth, learn to use code tags (see above). In your case, it isn't a big deal, but you're going to get farther if you learn to use them.

Code:

---

#include <iostream>
#include <string>
#include <cstdlib>    // system call

inline void pause() { system("PAUSE"); }

int main(void)
{
std::string name;

std::cout << "Enter your name: -> ";
std::cin >> name;

std::cout << "\nHello, " << name << "!" << std::endl << std::endl;

pause();
return 0;
}

---

Research the difference between <iostream.h> and <iostream>, et. al. These have to do with the C++ Standard and there are a ton of references on this site that deal with it.

P.S. Darn it, Kermi, I've got to learn to type faster! :D

MSVC++ colors keywords blue (by default)... "string" is not a keyword :)

But in the book I have(C++ for Dummies)it says that int,float,double,char,string,and long are variables.
And when I put any of them in the code they turn blue but string doesent.

So what is the variable for when I want the computer to remember a word?

>But in the book I have(C++ for Dummies)it says that int,float,double,char,string,and long are variables.
No, all of the above are data types you use data types to define variables which contain the appropriate data. The reason string isn't blue is because it is a user defined type found in a library, not a built-in type defined by the language itself. Your compiler doesn't color the names of user defined types because they are identifiers, not keywords.

>So what is the variable for when I want the computer to remember a word?
You can either use an array of characters terminated by the nul ('\0') character, or a user defined type like std::string.

Those are types of variables... a variable has to have a type so that the computer knows how to handle it and how much memory to allocate for it. A variable of type int (int x;) is a variable that can hold ints (integers). A char holds 1-byte values (commonly used for single characters because 1-byte = 8-bits = 256 possible values, which works nicely for the latin character set). A float holds single-precision floating point variables (like 1.2). A double holds double-precision floating point variables (like 3.14). A string holds null-terminated arrays of characters.

Uhm... you may want to get some beginner C++ books.
