Pointers Practice Questions

The questions below are designed to help you get more comfortable working with pointers in C++. Take your time with each one and do your best to complete them fully. Each question should be written in its own .cpp file. Once you’re done, feel free to share your solutions in the community for feedback and peer review.

Question 1: Allocate and Free a Single Integer Using new

Write a program that uses dynamic memory to store a single integer.

First, use new int to allocate memory for the integer and store the value 42 in it. Then print the value stored in the dynamically allocated memory. After that, properly free the memory using delete, and finally set the pointer to nullptr.
