- Activity 20 Electric Bill: Using Switch Statement, write a program that will calculate and show bills of the Manila Electric Company. The rates vary depending on whether the use is residential (R), commercial( C) , or industrial (I). Any other code should be treated as an error. The program should accept the subscriber ID, Subscriber Name, his total electrical consumption in a month, and the code of the consumer type. The rates are computed as follows: R: 50 plus .50 per kwh used C: 100 for the first 1000 kwh and 0.45 for each additional kwh I: 180 for the first 1000 kwh and 0.75 for each additional kwhWhat is the value of name after the following steps are executed? float name, x=20.5; float *a = &x; *a=2* (*a); *as name8.

- Programming Assignment: Car Repair For this programming assignment, create a car repair program that prompts the user to enter information about a customer, the customer's vehicle, and the work performed on the customer's vehicle. Your program should then display the final car repair bill on the computer screen. Your program should accomplish the following: 1. Prompt the user to enter the following information: a. Information about the customer (name, street address, city, state, zip code, phone number). b. Information about the customer's vehicle (make, model, year). c. Information about the work performed (brief description, labor hours needed, cost of parts). 2. Use a labor cost amount of $100.00 per hour and a sales tax rate of 7.0%. 3. Calculate the following: Variable subtotal sales tax total repair bill amount Formula subtotal = labor cost per hour * number of labor hours sales tax = sales tax rate * subtotal total repair bill amount = subtotal + sales tax 4.

Part1: Determine correct quadrant for angle Complete the program below so that it prompts the user for an angle in degrees, and prints out the quadrant in which the angle is located, represented by Roman numerals, as shown in the following figure. 180⁰ II E III 90⁰ 270⁰ IV Notice that the value of the angle starts at zero degrees at the rightmost point of the circle, moving counterclockwise around the circle as the number of degrees grows. For instance, if the input angle has 100 degrees, it is in quadrant II, while an angle of 300 degrees is in quadrant IV and an angle of 45 degrees is in quadrant I. Each quadrant contains 90 degrees and starts at a multiple of 90. For example, 89 degrees is in quadrant I and 90 degrees is in quadrant II. All the input angle values must be integers between 0 and 359.
