Question
The following functions/statements are useful to solve the probler: • The pow function from the <math.h> library: e.g. pow(x.y) gives the value of x • The rand( ) function from the <stdlib.h> library: rand( ) gives a random integer between 0 and RAND_MAX, where RAND_MAX is a predefined constant integer in C++. When you use rand( ) make sure to include the empty braces (you will understand what they mean later when you learn about C++ functions). The srand(time(0)); statement at the beginning of main which requires adding the <time.h> library. This statement is needed if you want the program to give different random values for different runs. The use of srand(time(0)) is optional; i.e. no grades will be deducted if you do not include it.

Write a C++ program that performs the following (see the Appendix for useful functions): (a) Prompt the user to enter two positive integers n and m (you are not required to handle the case when n or m are not positive), and a real number z (z is real, i.e it can be a decimal and it can be negative). Read the values entered by the user and store them in variables of appropriate data types. (b) Ask the user to enter one of two choices: - 'd' or 'D' for deterministic sum - T' or 'R' for random product o If the user's choice is a deterministic sum, then compute and print the following summation (where n, m, and z are the values entered in part a): m+n k det sum = 2( (-1)*) z x k k=n o Otherwise, if the choice is a random product, then compute and print the following random product (where n, m, and z are the values entered in part a, and rg is a random decimal number between 0 and 1 inclusive): m+n []a +r) rand prod = z x (1+ k=n Note: Notice that rg depends on k, this means that you need to generate a new random decimal in the range [0,1] for each k. o If the user enters an invalid choice (any character other than 'd', 'D', 'r', or 'R'), print an error message. (c) Update the program to allow the user to repeat (enter new values of n, m, and z, and a new choice), and display the new results for the new inputs. Your program will never stop (it will keep asking the user for new input after each run)
