Question

c++

Write a program that print stars, Max and Min values. It should use the following functions:

1. (2 pts) int getNum ( ) should ask the user for a number and return the number. This function should be called by main once for each number to be entered. Input Validation: Do not accept numbers less than -100.
2. (2 pts) void printStars ( int n ) should print n number of stars. If n is less than 0, display "Invalid" message instead.
3. (5 pts) main ( ) should call getNum ( ) function each time to read the user input. Pass each user input into printStars ( ) function to print stars. This function will loop to process series of integers.
   • (2 pts) When the user input is -99, that's a signal to terminate the loop (end of the user inputs (sentinel value)). Remember, sentinel value should not be processed as part of user inputs.
   • (2 pts) main ( ) should also display overall Min and Max values of user inputs.
4. (1 pt) Write the function prototypes for getNum ( ) and printStars ( ) functions.

Sample runs :

(Bold underlined numbers below are sample user inputs. Your program should display the exact output given the same user inputs)

Please enter a number : -99
Exiting the program....

// restart the program here and the output is as follows: 
Please enter a number : 1
*
Please enter a number : 2
**
Please enter a number : 3
***
Please enter a number : -99

Min = 1, Max = 3
Exiting the program....

// restart the program here and the output is as follows: 
Please enter a number : -1
Invalid
Please enter a number : 10
**********
Please enter a number : -33
Invalid
Please enter a number : 5
*****
Please enter a number : -99

Min = -33, Max = 10
