C++ programming problem:
During the tax season, every Friday, the J&J accounting firm provides assitance to people who prepare their own tax returns. Their charges are as follows:
a. If a person has low income (<=25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes.
b. For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regularly hourly rate for the time over 20 minutes.
Write a program that prompts the user to enter the hourly rate, the total consulting time, and whether the person has low income. The program should output the billing amount. Your program must contain a function that takes as input the hourly rate, the total consulting time, and a value indicating whether the person has low income. The function should return the billing amount. Your…

- (Physics) a. The weight of an object on Earth is a measurement of the downward force onth e object caused by Earth’s gravity. The formula for this force is determined by using Newton’s Second Law: F=MAeFistheobjectsweight.Mistheobjectsmass.AeistheaccelerationcausedbyEarthsgravity( 32.2ft/se c 2 =9.82m/ s 2 ). Given this information, design, write, compile, and run a C++ program to calculate the weight in lbf of a person having a mass of 4 lbm. Verify the result produced by your program with a hand calculation. b. After verifying that your program is working correctly, use it to determine the weight, on Earth, of a person having a mass of 3.2 lbm.arrow_forward(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.arrow_forward(General math) a. Design, write, compile, and run a C++ program that calculates and displays the area of a triangle, such as the one in Figure 2.18, with a base of 1 in and a height of 1.5 in. The area is given by this formula: Area=12(base)(height) b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the area of a two-dimensional triangle with a base of 3.5 in and a height of 1.45 in.arrow_forward
- (General math) The volume of oil stored in an underground 200-foot deep cylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume=radius2(200distance) Using this information, write, compile, and run a C++ program that accepts the radius and distance measurements, calculates the volume of oil in the tank, and displays the two input values and the calculated volume. Verify the results of your program by doing a hand calculation using the following test data: radius=10feetanddistance=12feet.arrow_forward(General math) a. Write a C++ program to calculate and display the value of the slope of the line connecting two points with the coordinates (3,7) and (8,12). Use the fact that the slope between two points with the coordinates (x1,y1)and(x2,y2)is(y2y1)/(x2x1). b. How do you know the result your program produced is correct? c. After verifying the output your program produces, modify it to determine the slope of the line connecting the points (2,10) and (12,6). d. What do you think will happen if you use the points (2,3) and (2,4), which results in a division by zero? How do you think this situation can be handled? e. If your program doesn’t already do so, change its output to this: The value of the slope is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.arrow_forward(General math) The perimeter, approximate surface area, and approximate volume of an in-ground pool are given by the following formulas: perimeter=2( length+width)volume=lengthwidthaveragedepthundergroundsurfacearea=2( length+width)averagedepth+lengthwidth Using these formulas as a basis, write a C++ program that accepts the length, width, and average depth measurements, and then calculates the pool’s perimeter, volume, and underground surface area. In writing your program, make these two calculations immediately after entering the input data:lengthwidthandlength+width. The results of these two calculations should be used as needed in the assignment statements for determining the perimeter, volume, and underground surface area without recalculating them for each equation. Verify your program’s results by doing a hand calculation, using the following test data :length=25feet,width=15feet,andaveragedepth=5.5feet. After verifying that your program is working, use it to complete the following chart:arrow_forward
- (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: //Determinethenumberof100lbweightsw100=int( WEIGHT/100)//Determinethenumberof50lbweightsw50=int( ( WEIGHTw100100 )/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.arrow_forward(Electrical eng.) The amplification of electronic circuits is measured in units of decibels, which is calculated as the following: 10LOG(Po/Pi) Po is the power of the output signal, and Pi is the power of the input signal. Using this formula, write, compile, and run a C++ program to calculate and display the decibel amplification, in which the output power is 50 times the input power. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the amplification of a circuit, where output power is 4.639 watts and input power is 1 watt.arrow_forwardGeneral math) a. Write a C++ program to calculate and display the midpoint coordinates of the line segment connecting the two endpoints given in Exercise 1a. Use the fact that the coordinates of the midpoint between two points with the coordinates x1,y1)and(x2,y2)are((x1+x2)/2,(y1+y2)/2). Your program should produce the following display (replacing the underscores with values your program calculates): ThexmidpointcoordinateisTheymidpointcoordinateis b. How do you know the midpoint values your program calculates are correct? c. After verifying the output your program produces, modify it to determine the midpoint coordinates of the line connecting the points (2,10) and (12,6). d. If your program doesn’t already do so, change its output to this: The x coordinate of the midpoint is xxx.xx The y coordinate of the midpoint is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.arrow_forward
