Please check if the following answers help in giving you clarity about this.

Static array vs. dynamic array in C++

Static arrays are created on the stack, and necessarily have a fixed size (the size of the stack needs to be known going into a function): int foo[10];

Dynamic arrays are created on the heap. They can have any size, but you need to allocate and free them yourself since they're not part of the stack frame: int* foo = new int[10]; delete[] foo;

You don't need to deal with the memory management of a static array, but they get destroyed when the function they're in ends

Array size at run time without dynamic allocation is allowed?

C99 standard (http://en.wikipedia.org/wiki/C99) supports variable sized arrays on the stack. Some of the compilers might implement these standards and support variable sized arrays.
