I'm a little confused with this because in a tutorial I read it said that this variable will only hold 1 character. If this is true how do I make it hold more, or is there another variable I could use.thanks

you could ether use character arrays

code:

char letter[10];

or use string

code:

#include<string.h>

String word;

Just one comment on this. The class name is "string". All lowercase. Second, it's in the std namespace, so unless you're "using namespace std;", you should fully qualify the name.

code:

#include <string>

int main()
{
std::string word;
}

no... just have using namespace std; and just declare it by having string str;

Yeah, it's convenient, but it's best to use "using namespace" very selectively.

Instead of:

code:

#include <string>

using namespace std;

int main()
{
string str;
}

Write something like:

code:

#include <string>

int main()
{
using namespace std;

string str;
}

That way it doesn't affect the entire program. After all, you might create another class named "string" elsewhere, and using the full name (std::string vs. util::string in a program I was writing today) will help avoid collisions.

code:

using std::string;

then only the string name is taken not all the std ones

nice.. those are the things i like doing.. but.. i have no time heh for what language.. or have u designed ur own language as well ? i have designed the perfect language in mind.. after looking at Perl, java, c++, obj-c and python wow you can only imagine the language i have in mind.. (not necessarly bloated like c++ if that what ur thinking, it's more like perfect, well atleast to me)

I'm writing it in C++. Templates and the STL really cut down the amount of work I have to do. I'd love to do it in Obj-C or Eiffel, but Eiffel doesn't have unsigned integer types, and Obj-C doesn't have templates. And clean C++ (without any C cruft) is actually really nice to develop in.
