Difference between delete and delete[]?..

Answer / sachin mahajan

When we want to free a memory allocated to a pointer to an
object then "delete" is used.
Ex
int * p;
p=new int;
// now to free the memory
delete p;
But when we have allocated memory for array of objects like
int * p= new int(10); //pointer to an array of 10 integer
then to free memory equal to 10 integers
delete []p;
NOTE: One can free the memory even by "delete p;" But it
will free only the first element memory.

element but will free up the whole block. More info at:
