Question

I have an array of ints:

int a[1];

I then want to make the items in a be pointers to the next dimension of arrays.

a[0] = new int b[3];

Would I then be able to use the double bracket indexing?

a[0][0] = 1; //Assign 1 to b[0]

Answer 1

If you want to make items in a array, then you have to define it that way.

int *a[1];
a[0] = new int[3];

Or similary

int a[1][3];

Or

int **a;
a = new int *[1];
a[0] = new int[3];

But as you you have c++ tag, you should rather use std::vector (or std::array in c++11).
