Chapter 3, Problem 12PP

(General math) a. A balance has the following weights: 100 lb, 50 lb, 10 lb, 5 lb, and 1 lb. The number of 100 lb and 50 lb weights required to weigh an object weighing WEIGHT pounds can be calculated by using the following C++ statements:

/ /   D e t e r m i n e   t h e   n u m b e r   o f   100   l b   w e i g h t s w 100   =   i n t ( W E I G H T / 100 ) / /   D e t e r m i n e   t h e   n u m b e r   o f   50   l b   w e i g h t s w 50   =   i n t ( ( W E I G H T     w 100   *   100 ) / 50 )

Using these statements as a starting point, write a C++ program that calculates the number of each type of weight needed to weigh a 789 lb object.

b. Without compiling or running your program, manually check the effect of each statement in the program and determine what’s stored in each variable as each statement is encountered.

c. After verifying that your algorithm works correctly, compile and run your program. Verify that the results your program produces are correct. After verifying that your program is working correctly, use it to determine the weights required to weigh a 626 lb object.

(C PROGRAMMING ONLY) 6. Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount.   In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer.   Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1. Inputted integer Output Enter value: 6132450351503022244
2. (Guess the Number) Write a C program that plays the game of "guess the number" as fol- lows: Your program chooses the number to be guessed by selecting an integer at random in the range 1 to 1000. The program then types: 5.32 I have a number between 1 and 1000. Can you guess my number? Please type your first guess. The player then types a first guess. The program responds with one of the following: 1. Excellent! You guessed the number! Would you like to play again (y or n)? 2. Too low. Try again. 3. Too high. Try again. If the player's guess is incorrect, your program should loop until the player finally gets the number right. Your program should keep telling the player Too high or Too low to help the player “zero in" on the correct answer. [Note: The searching technique employed in this problem is called binary search. We'll say more about this in the next problem.]
Language: C++ (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? Write a program that prompts the user to enter: The total number of units. The rent to occupy all the units. The increase in rent that results in a vacant unit. Amount to maintain rented unit. The program then outputs the number of units to be rented to maximize the profit.   Note: Please include the pseudocode
