Return a Pointer to a Dynamically Allocated Array in C++ In C++, dynamic memory allocation allows the program to allocate memory at runtime rather than compile time. The new operator is used to dynamically allocate memory for data structures, such as arrays. Conversely, the delete operator deallo...

In this program, the elements are stored in the integer array data[]. Then, the elements of the array are accessed using the pointer notation. By the way, data[0] is equivalent to *data and &data[0] is equivalent to data data[1] is equivalent to *(data + 1) and &data[1] is ...
