Hello all,

I am new to C++.



Question #1: What the problem is:

============

I have Dev-Cpp 4.9.9.2 on Windows 7/64 bit.

I am trying out code from http://www.cplusplus.com/reference/vector/vector/data/ on it.

It fails with

main.cpp:42: error: 'class std::vector<int, std::allocator<int> >' has no member named 'data'



--->Is the website code wrong and there is no vector::data()?

--->Is the package of Dev-Cpp wrong?

--->Both?



Question #2: Why the problem is:

============

I need help in solving this for Sudoku solver program.

I store row, column and box as vectors and need to find an intersection of the trio.

As I understand from examples from http://www.cplusplus.com, in order to use std::set_intersection, I need to pass two arrays with lengths and a vector to store the difference.

This forces me to convert row, column and box into arrays using vector::data(), which fails.



--->Is there a way out without using vector::data()?



Thanks in advance!
