Im creating a console for my game and im using STL''s string. The odd thing bout the string is sometimes just crashes randomly. I think the errors occure when use: Insert() function copy one string to another do any of you know how to get round this error? thanx in advance Iain

Which insert() function ? How did you make the copy ?
Do you have a minimal test case that crashes ?

<pedantic> The std::string class is part of the C++ standard library, but not of the STL </pedantic>

std::string is part of both. Having said that, I'd prefer it if people stopped referring to it as "STL string" (which also happens with vector and friends), since there's often an implication string is somehow an optional add-on to C++ and not actually a part of the Standard Library.

ok im using the C++ standard libary string

to copy the string''s I just use the = operator

String1 = String2;

I use insert to insert 1 character, ie:
insert(m_Cursor,1,result);

they seem to cause it to crash. I don''t use empty anymore but that also caused it to crash.

Note that insert & operator= don''t crash every time, sort of when I reach a certain position.

maybe m_cursor is illegal argument at times

The overloaded string& std::insert( size_type idx, size_type num, char c) fails if idx > size(). If you somehow corrupt the string, it may crash on any operation.

Hang on, doesn''t STL stand for "Standard Template Library"? I always thought "STL" and "C++ Standard Library" were interchangeable?

If I had my way, I''d have all of you shot!

Not interchangable. The Standard Template Library was incorporated as part of the C++ standard library, but there are parts of the standard library that are not parts of the STL, like locales.

Not every class template is part of the STL, even though the string classes do qualify as a STL-compatible container (of char, wchar_t, unsigned char... whatever

).

The C++ standard library includes

- the C standard library (yup)
- the Standard Template Library (STL)
- strings
- iostreams (NOT the old iostream.h)
- complex numbers
- valarrays
- auto_ptr
- locales

The STL consists in
- containers
- iterators
- algorithms
- functors
- allocators

And probably more stuff I have forgotten
