Is there a method in String class to convert a string to an int?

Is there a method in String class to convert a string to an int?

Hi,
Is there a method in String class to convert a string to an int?
In C, there is atoi function. How about in C++?

Use std::istringstream for this.

Hi.

As much fun as this is (or better: was), this is not the 
"learning c++ for dummies" mailing list or forum. 

Your questions are off topic here since this mailing list
deals specifically with issues regarding GCC - the Gnu 
Compiler Collection. If I'm not seriously mistaken, your
postings never included the word gcc or g++ which is usually
quite a strong indication that you posting to the wrong list.

And WHY don't you get a good book on C++? This can't be so hard.
I mean, if you don't want to buy, maybe you can borrow it from
someone. 

And then, take the time and read it. If you don't understand
something, just read it again. Usually it gets clearer on the
second or third read. 

If you still have problems understanding something you surely
should seek help from more experienced people. A good forum
for your questions on usenet would be e.g.:

comp.lang.c++  OR
comp.lang.c++.moderated

There are also a lot other resources, web based forums and 
references out there. E.g.:

http://www.icce.rug.nl/documents/cplusplus/
http://www.cprogramming.com/

Also, since you're using GCC (at least I assume that) it is all 
open code and you can have a look at the string class whether
it has a function returning an integer representation of its
value or not. Also there are a few C++ STL online references 
out there you could have read. Just search the web.

Kind regards,

Hi,

Use std::istringstream or BOOST lexical_cast.
