std::string array

[SKSNET]

Hi there,
I am wondering that can a class member be an array of string. I can create an 2d array of char but I really want to use an array of std::string. Can any body help me out?

NB: This is my first time posting any thread in any forum. I am not sure that I could explain my question. Please ask me if you need further details.

You can create a 2D array of strings, sure. If you have one of chars already, just replace char with string in the declaration. There is an issue with dynamic allocation and default constructors (you'd better supply one if you don't use {entry, entry} notation) since the arguments can't be passed to the constructor. Also, before weaknessforcats gets in here, read this howto on arrays in C/C++.

[CODE=cpp]
string mat[3][4];
[/CODE]

Thanx a lot for your help.

You create an array of strings by using a vector.

[code=cpp]
vector<string> arr;
[/code]

A vector is implemented as a array. The vector member functions are the same functions you would need to write to use your C++ array. Why do the work over again?
