- (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?(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=FA(n) __________ is an array of characters.
- (Practice) Write correct notation for the first, third, and seventh elements of the following arrays: a. int grades[20] b. double volts[10] c. double amps[16] d. int dist[15] e. double velocity[25] f. double time[100]C program for the longest sequence of increasing numbers for one array. Use the function: void longestSequence(int b[], int sizeB)2. You are given an array of integers below, in one operation you can choose any two numbers x, k and add the number x to the first k elements of the array. Write a program to find the minimum sum of Ix after you perform all operations such that all elements of the array become equal after the operations. Given array: [1,4,2,1] Expected Output: 6 Language: C++/Python
