What is a dynamic array in C++?

A dynamic array is quite similar to a regular array, but its size is modifiable during program runtime. DynamArray elements occupy a contiguous block of memory. Once an array has been created, its size cannot be changed. A dynamic array can expand its size even after it has been filled.

When is memory allocated for an array?

An array is a contiguous space of memory allocated for storing some data. We know when variables are declared, computer’s memory is allocated for them. A similar process takes place when arrays are declared except that size of the memory allocated is greater, depending on the size of the array.
