class with multidimensional array in C++

This program has also been given in examples of array, in which some basic tasks have been done with elements of multi-dimentional array.

Here in this program, using the class and switch statement has been tried to improve the program. Two user defined functions have been used in the program. Whose definition is defined within the class in a way inline definition.

Also the appropriate comments in the program Given, so that the implementation of the program can be understood.
