Question: The file Labll vl.cpp provided on Canvas creates an array of ten ContactType objects. But a user might prefer to store more than or fewer than ten contacts in a contact book. Our task is to amend the program to let the user choose how many contacts to store. We will then dynamically allocate the appropriate amount of memory and populate the array with the number of contacts the user specified. To accomplish this, please make these following changes 1) 2) Inside main), create an integer variable called length, and prompt the user to enter a 3) Comment out or delete the statement: ContactType-contactBookARR LENGTH] Replace it The array will no longer be the predetermined length 10. Please comment out or delete the statement: const int ARR LENGTH 0 desired number of contacts. Store that user input in length with a statement that uses a ContactType pointer to point to a newly allocated array of the exact length specified by the user 4) Rewrite the for-loops, condition: for (int - 6;
