Chapter 3, Problem 3.15E
State which of the following are true and which are false. If a statement is false, explain why.
- Experience has shown that the most difficult part of solving a problem on a computer is producing a working C
program. - A sentinel value must be a value that cannot be confused with a legitimate data value.
- Flowlines indicate the actions to be performed.
- Conditions written inside decision symbols always contain arithmetic operators (i.e., +, -, *, /, and %).
- In top-down, stepwise refinement, each refinement is a complete representation of the
algorithm .

Direction: Read each sentence/ situation carefully and select the BEST answer among the choices.
1. It is a Boolean expression that tells when the loop will exit.
2. The sequence that makes up the loop body may either be a block of Turbo C statements or a single Turbo C statement.
3. In Turbo C it is a reserved word.
4. Its values determine the number of times the loop iterates.
5. It is the second type of open-ended loop.

- Problem Description The greatest common divisor, also known as GCD, is the greatest number that will, without a remainder, fully divide a pair of integers. Now, I want you to make a program that will accept two integers and with the use of loops, print out their GCD. Make good use of conditional statements as well. Input A line containing two integers separated by a space. 6·9 Output A line containing an integer. 3arrow_forwardC++Jesse the Body-Building Burglar Jesse has broken into a sporting goods store to steal some training equipment. He can only carry out a certain amount of stuff before it gets too heavy. In addition, Jesse can only make one trip in and out of the store before the cops arrive, so he wants to be sure to get the most value out of the stuff he takes. Input for the program will be as below. The first line will contain how much Jesse can carry. This line is followed by a single item per line. Each of these lines will contain the name of the item, the number of items available, each individual item’s weight and its value. There will be up to 10 different items. Output the number of each item type he should take to maximize his value as well as the max value.

Valid test score entries are between 0 and 100 inclusive. The program should display a welcome message and run everything through the "main" function. have the ability to enter several test scores (try a loop) and print out the total score, as well as, the average score. continuously ask for test scores until the number 99.9 has been entered. test for valid entries and the value 99.9. If a test score is valid, the program should add the current score to the total score and update the number of test scores by one (+1), otherwise it displays an error message. Note : This assignment involves the use of a while loop and if-else decision making controls. You CANNOT use the reserved keywords break and continue for any portion of this program or any program for that matter throughout this course.arrow_forward

- Use C++ Programing language. Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Charges for hospital services (lab tests, etc.) Hospital medication charges If the patient was an outpatient, the following data should be entered: Charges for hospital services (lab tests, etc.) Hospital medication charges Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the…arrow_forward(Data processing) Years that are evenly divisible by 400 or are evenly divisible by 4 but not by 100 are leap years. For example, because 1600 is evenly divisible by 400, 1600 was a leap year. Similarly, because 1988 is evenly divisible by 4 but not by 100, it was also a leap year. Using this information, write a C++ program that accepts the year as user input, determines whether the year is a leap year, and displays a message telling the user whether the entered year is or is not a leap year.arrow_forward(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d.

The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward
