Chapter 5.1, Problem 5E
(For review) a. What’s the difference between a pretest and posttest loop?
b. If the condition being tested in a pretest loop is false, how many times are statements in the loop executed?
c. If the condition being tested in a posttest loop is false, how many times are statements in the loop executed?

Alter the program segment that generates n random numbers between 1and n. The new program too should generate numbers between 1 and n. Ifnumber being generated is equal to n/2 the control should terminate theloop. Otherwise, a new number between 1 and n should be generated. (thisloop should repeat maximum of 1000 times). When the program exits fromthe loop, if n/2 is not generated, it should display “could NOT generate”. If n/2is generated, it should display “could generate on the xth try”.
(Removing break and continue ) A criticism of the break statement and the continue statement is that each isunstructured. Actually, these statements can always be replaced by structured statements, although doing so can beawkward. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent. [Hint: The break statement exits a loop from the body of the loop. The other way to exit is by failing the loop-continuation test. Consider using in the loop-continuation test a second test that indicates “early exit because of a ‘break’ condition.”] Use the technique you develop here to remove thebreak statement from the application.
(Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied.
However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance.
How many units should be rented to maximize the profit?
Instructions
Write a program that prompts the user to enter:
The total number of units.
The rent to occupy all the units.
Amount to maintain a rented unit.
The increase in rent that results in a vacant unit.
The program then outputs:
The number of units to be rented to maximize the profit
The maximum profit
Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

- (C PROGRAMMING ONLY!) Your task is to fill in the blank with the correct condition. 5. Finding the Impostorby CodeChum Admin There's this Dog game I played where a group of Dogs gather together and complete missions. One of them though is an impostor because it is not a real dog; its breed is not a dog breed. Your task is to find that impostor. To do this, you need to check Instructions: In the code editor, you are provided with the enum, DogBreed. Furthermore, an initial main() code is provided for you where the user is asked for what the breed of the Dog.Then, in lines 18 - 22, a partial code to check if the breed is valid or not is given.Your task is to fill in the blank with the correct condition. Make sure to use the values of the enum, DogBreed in checking. Input 1. Dog Breed Output Input the breed of the dog: 2Yup, the breed is validarrow_forwardQuestions:1. A criticism of the break and continue statements is that each is unstructured. These statements can always be replaced by structured statements. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent.

Write a program that uses for statements to print the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks (*) should be printed by a single statement of the form cout << '*'; (this causes the asterisks to print side by side).

In response to a prolonged recession, one companyhas cut its customers’ credit limits in half. Thus, if a particular customer had a credit limit of $2000,it’s now $1000. If a customer had a credit limit of $5000, it’s now $2500. Write a program thatanalyzes the credit status of three customers of this company. For each customer you’re given:a) The customer’s account number.b) The customer’s credit limit before the recession.c) The customer’s current balance (i.e., the amount the customer owes the company).Your program should calculate and print the new credit limit for each customer and shoulddetermine (and print) which customers have current balances that exceed their new credit limits.arrow_forward(Apartment problem) A real estate office handles , say, 50 apartment units.
