Please write the program with c++ language, and provide a output example, print everything in the main not inside any function

Write a program that declares an integer array of size 8 using dynamic memory allocation. Then, the program keeps asking for numbers from the user to put inside the array until a negative number is entered.

If the user enters more than 8 numbers, the program MUST increase the size of the array ONE BY ONE using realloc method. Finally, the program will write all the numbers inside the array
