Need helps on C++ attach. Thanks

Pointers with classes a) A user-defined class named Timer has a constructor that takes two integer parameters to initialize hour and minute data members. Write a single C++ statement to create an object of the Timer class using dynamic memory allocation and assign it to a pointer variable named timePt r. It should call the constructor with two parameters. Use values of 10 and 20 for hour and minute respectively. b) Write the definition for a function named randArray that takes a single integer argument, n, and returns a dynamically allocated array of n pseudo-random integers. You may assume the pseudo-random number generator has been previously declared and seeded, (i.e. you do not need srand(time(0)) or an include.) c) Now write C++ statements to call the randAr ray function to construct a 100 element array, then print the array values to the display (one per line) and delete the dynamically allocated array
