Re: Dynamic arrays

["Ken Hsu" <kenchsu@gte.net>]

multi-dimensional array works in the same way for C++, in C you simply
allocate enough memory to hold the amount of elements that are required for
your multidimensional array using malloc.

// dim1 and dim2 are dimensions of the array
// c++
ptrArray = new char[dim1][dim2];

// c
ptrArray = (char*) malloc(sizeof(char)*dim1*dim2);

if you look up these keywords in a c or c++ reference books or on the web,
they should point you to examples of how to create dynamic arrays.

Hope this helps,


Ken
