Primitive-type local variables are initialized by default. State whether the statement is true or false. If false, explain why.
Programing Language: C++
Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time.
A time is specified in your program with three variables:
int hours, minutes;
bool isAM; // You can also use a char, i.e. A or P
for example, to represent 11:50 PM, you would store:
hours = 11,minutes = 50, isAM = false or if using a char, hours = 11,minutes = 50, isAM = 'A'
This means that you need six variables to store a start and future time.
Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as parameters that represent the start…

Main Idea
The Basal Metabolic Rate (BMR) is the amount of energy (calories) your body needs while resting. This accounts for about 60 to 70 percent of calories burned in a day. In general, men have a higher BMR than women. One of the most accurate methods of estimating your basal metabolic rate is the Harris-Benedict formula:
Adult_Male_BMR = 66 + (6.3 x bodyweight in lbs.) + (12.9 x height in inches) - (6.8 x age in years)
Adult_Female_BMR = 655 + (4.3 x weight in lbs.) + (4.7 x height in inches) - (4.7 x age in years)
In this lab, you will be given the function calculate_calorie_intake and you will be required to write the body of the test functions test_calculate_calorie_intake_negative, test_calculate_calorie_intake_1, test_calculate_calorie_intake_3. In these functions, you will write function calls to calculate_calorie_intake…

- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls.

- joyce farrell solutions, do u have the programming exercise answers/ debugging exercises ? 9th edition example : "Write a program that declares a variable named inches, which holds a length in inches, and assign a value. Display the value in feet and inches; for example: 86 inches is 7 feet and 2 inches. Be sure to use a named constant where appropriate."arrow_forwardC++ Programming Exercise: When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first month's interest on $1,000 is 1000 X 0.006 = 6. Becuase the payment is $25 and the interest of the first month is $6, the payment toward the principal amount is 25-6 = 19. This means after making the first payment, the loan amount is 1,000-19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 X 0.006 = 5.886,…arrow_forwardMathematical functions introduced in chapter 4 can be used in the mathematical calculations and simulations of the engineering and scientific problems.
