How to define a new class "Matrix" based on "Vector<Vector< T>>"?

[herbu]

In order to automatically check if the index of an array declared by vector<T> exceeding its boundary, we define the class "Vector" derived from "vector" and do the operator overloading as shown in Vector.h. And it works well.
However, when we need to use the 2-dimensional array, we need to write more than 5 lines in order to initialize the 2-D array, as shown in main.cpp.

My question is: is there any way to define a new class "Matrix" which enjoys the ability of "Vector" for automatically checking the array boundary. and its declaration and initialization could be as simple as:

Matrix<double> tmp;
tmp.assignName( "tmp", 3, 4, 0.00);

-----------------------------------------------------
Many thanks for the helps.

"Vector.h" and "main.cpp" could be seen in tmp.zip.

Best regards,
Herbu.

Herbu,

The code looks pretty good that make it hard for me to give advice:) Perhaps you can think of removing the member variable tmp of type Vector in Matrix class which i can not see any usage of it.. Besides adding a print method both for Vector and Matrix class may be helpful in using them.. print method of Vector can simply print all elements it holds, while Matrix's print method iterates and calls the member vector's elements' print method and adding a newline at the end of each..
