char

[aliveiswell]

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.

y would u create another string class???

[Catalyst]

i like

code:

using std::string;

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

I'm writing a virtual machine interpreter. The "string" type for the VM is the 32-bit location of the string in memory and its 32-bit length.

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.
