C++ delete[]: Deallocating Dynamically Allocated Arrays - A Comprehensive Guide

In C++, delete[] is used to deallocate memory that was allocated using the new[] operator. It is used specifically when dealing with dynamically allocated arrays.

Here is an example of how delete[] is used:

int* dynamicArray = new int[5]; // allocate memory for an array of 5 integers

// use the dynamicArray...

delete [] dynamicArray; // deallocate the memory when it is no longer needed

Note that the delete[] operator is used with square brackets [] to indicate that it is deallocating an array, rather than a single object. It is important to use delete[] instead of just delete when deallocating dynamically allocated arrays to ensure that all elements of the array are properly deallocated.
