- For the C++ program show on the next page, answer the questions that follow. The names g, j, x, and y are declared multiple times. Distinguish uses of these names using line numbers where they were declared as subscripts. a. At point A in the program, what names are in scope? b. At point A in the program, what variables are live? c. At point B in the program, what names are in scope? d. At point B in the program, what variables are live?arrow_forwarddef area(side1, side2): return side1 * side2s1 = 12s2 = 6 Identify the statements that correctly call the area function. Select ALL that apply. Question options: A print(f'The area is {area(s1,s2)}') B answer = area(s1,s2) C result = area(side1,side2) D area(s1,s2)arrow_forwardc++ Write a program to use enumeration type to represent the seven colors of the rainbow, i.e. red, orange, yellow, green, blue, indigo and violet, as the enumerators in sequence, and red starts from 1. Then, ask the user to choose a value between the range of 1 – 7. If the user enters 3, the output will tell the user yellow has been chosen, and also display the previous and next colors of the chosen colors. If the user enters 1 or 7, display the chosen color and only next/previous color is displayed accordingly. Write the program in an infinite while loop, until a number which is beyond the range of 1 – 7 is entered. The sample output is as follows, Enter a number in the sequence of the rainbow color (1-7): 7 Violet is chosen. The previous color is indigo. Enter a number in the sequence of the rainbow color (1-7): 1 Red color is chosen. The next color is orange. Enter a number in the sequence of the rainbow color (1-7): 3Yellow is chosen. The previous color is orange and next…arrow_forward

Since, we do not have access to sensors, we will have to generate data via code. The plotting a sufficient number of these data points (500 in this case) should get the following diagram or something very similar: You will pick a quantity that you would like to simulate (such as temperature, humidity, barometric pressure, customers arriving at a mall, or just with an alternate descriptor) and decide what shape you will emulate. This will guide you in selecting sensible value base lines for your data values. e.g., If you pick inside temperature then normal range will be 18-21oC. Design and build a class that will model your sensor reasonably well. Notice how the peaks do not occur at regular interval, nor are they the same height. Even the squiggles are the same shapes. You will create a class with a single public member (property) that give you a “random” value in your intended range and…arrow_forward
