vector as a Member Data of a Class

[stdq]

Hi, everyone! If I want a class with a vector data member, can I specify it as follows?

std::vector< bool > integers( 101 )

I'm having some problems when compiling my code. Thanks in advance!

You are probably doing everything correctly.

Here's some C++ dirty laundry: A vector<bool> is not a vector!

Bits in C are usually handled using bitfields. So the vector<bool> uses bitfields, is not a template, has methods not in any real vector, is not an array.

Other than that, it works great (so I hear).

If you insist on bool, then bury the bool in a class and have a vector of that class.

Actually, I had to initialize the vector in respect to its size using a member intializer. But thanks for the info!

You are wandering into a swamp.

You will find that vector<bool> iterators can't be dereferenced nor an they be incremented.

vector<bool> is not an array so operator[] won't compile.

vector<bool> was a design error in C++ 1998 and is only kept for backwards compatibility. No new code is supposed to be written using this non-standard container.

You are supposed to use bitset<> for managing at the bit level.
