- (Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().(Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Volts
- (Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=F(Electrical eng.) Write a program that stores the following resistance values in an array named resistance: 16, 27, 39, 56, and 81. Your program should also create two arrays named current and power, each capable of storing five double-precision numbers. Using a for loop nd a cin statement, have your program accept five user-input numbers in the current array when the program is run. Your program should store the product of the values of the squares of the current array and the resistance array in the power array. For example, use power[1]=resistance[1]pow(current[1],2). Your program should then display the following output (fill in the chart):(Program) Write a declaration to store the following values in an array named rates: 12.9, 18.6, 11.4, 13.7, 9.5, 15.2, and 17.6. Include the declaration in a program that displays the values in the array by using pointer notation.
- Instructions: Using an array, enhance the program that you have performed in the previous exercise. The program should accept multiple entries and iteratively perform the following operations. Submit the source code and screenshot of output. Using a user-defined function and appropriate conditional and looping statements, create a program that will: (a) ask the item price from the user (b) ask how many items to purchase for a specific item price (c) ask if there are other items to purchase, if yes, repeat the first step, proceed to the next step if otherwise (d) compute and display for the total amount to pay (e) ask for the payment from the user (f) accepts only enough amount of payment, ask another payment if otherwise (g) compute and display changeInstructions: Using an array, enhance the program that you have performed in the previous exercise.

The values entered by the user only be between 0 and 100 and the program should validate these appropriately. The program should then: Display the average of the values Display the highest value in the array Display the lowest value in the array Discuss how the values should be validated. What control structures could be used?
- C++ PLEASE INCLUDE COMMENTS Write one program that does the following: Ask the user for ten (10) grades, and store the data in an array. Compute the average of all the grades. Print the original ten grades and the average. Declare an integer array with the name of “grades” of size 10 in the main function. Create a function called “getGrades” that prompts the User for the grades and puts them in an integer array. The function will receive an integer array and the size of the array. In the function prototype and the function header, call the array “gradeArray” and call the size of the array "size." iii. Create a For Loop that cycles through each cell of the array. At each cell prompt the User for a grade. Store the grade entered by the User into the array cell. From main, send this function the array called “grades” and the size of the array.

Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.
