how to properly delete a pointer to array

Question

I\'m new to C++, and I\'m confused about arrays and pointers. Could someone tell me how I can properly delete a pointer. Like for example,

int *foo;
foo = ne         


        

Answer 1

If you allocate an array of objects using the new [] operator then you must use the delete [] operator and therefore the non-array new can only be used with the non-array delete.

int *a = new int[10];
int *b = new int;

delete [] a;
delete b;
