Write code that dynamically allocates an array of 20 integers, then uses a loop to allow the user to enter values for each element of the array.

Question: Explain the steps involved in writing a program in C or C++ that dynamically allocates an array of 20 integers and allows the user to enter values for each element. Answer: To write a program that dynamically allocates an array of 20 integers and allows the user to enter values for each element, follow these steps: 1. Include necessary headers, such as `stdio.h` for input-output functions and `stdlib.h` for dynamic memory allocation functions. 2. Declare the main function as the starting point of the program. 3. Inside the main function, declare a pointer for the array and use the `malloc()` function to allocate memory for 20 integers. Ensure the allocation is successful by checking if the pointer is NULL. 4. Use a loop to iterate through each element of the array, prompting the user to enter a value for each element and using `scanf()` to store it in the respective array element. 5. After the loop, free the memory allocated earlier using the `free()` function and exit the program with a return code of 0 to indicate successful execution.
