Please answer it in c++ 4b QUESTION 4(a) Write a program that computes the average of numbers using arrays.The program should caleulate the average of the number of data fronl to 100.If the user enters a value of n which is above 100 or below 100 then the whileloop should be executed to request the user to reenter value of n until it isbetween I and 100.• When the numbers are entered by the user, subscquently the sum should becalculated and stored in the variable sum.• After storing all the numbers, average should be calculated and displayed.The program should take n number of elements from user (where, n isspecified by user), stores data in an array and calculates the average of thosenumbers.(b) Write a program that takes a string from the user and calculates the number ofvowels, consonants, digits and white-spaces.

START DECLARE vowels = 0, consonants = 0, digits = 0, spaces = 0 PRINT "Enter a line of string: "…

(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
(Numerical) a. Define an array with a maximum of 20 integer values, and fill the array with numbers input from the keyboard or assigned by the program. Then write a function named split() that reads the array and places all zeros or positive numbers in an array named positive and all negative numbers in an array named negative. Finally, have your program call a function that displays the values in both the positive and negative arrays. b. Extend the program written for Exercise 6a to sort the positive and negative arrays into ascending order before they’re displayed.
(Data processing) a. Write a program to input 10 integer numbers in an array named fmax and determine the maximum value entered. Your program should contain only one loop, and the maximum should be determined as array element values are being input. (Hint: Set the maximum equal to the first array element, which should be input before the loop used to input the remaining array values.) b. Repeat Exercise 8a, keeping track of both the maximum element in the array and the index number for the maximum. After displaying the numbers, print these two messages (replacing the underlines with the correct values): The maximum value is: ___ This is element number ___ in the list of numbers c. Repeat Exercise 8b, but have your program locate the minimum of the data entered.
(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?
(Practice) a. Write output statements using cout that can be used to display values from the first, third, and seventh elements of each array declared in Exercise 2. b. Write a for loop that can be used to display values for the complete array declared in Exercise 2.
(Practice) a. Write a declaration to store the string "This is a test" in an array named strtest. Include the declaration in a program to display the message using the following loop: for( i=0;iNUMDISPLAY;i++)coutstrtest[i]; NUMDISPLAY is a named constant for the number 14. b. Modify the for statement in Exercise 5a to display only the array characters t, e, s, and t. c. Include the array declaration written in Exercise 5a in a program that uses a cout statement to display characters in the array. For example, the statement cout << strtest; causes the string stored in the strtest array to be displayed. Using this statement requires having the end-of-string marker, \0, as the last character in the array. d. Repeat Exercise 5a, using a while loop. (Hint: Stop the loop when the \0 escape sequence is detected. The expression while (strtest[i]!=0)canbeused.)
(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.
(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
Program type C Write code that will fill the array a (declared below) with numbers typed in at the keyboard. Each line refers to an individual student’s quiz grades. So, there are 4 students with 3 grades that can entered through the keyboard. (The grades are out of 10)int a[4][3];For this assignment, create a function that calculates the average of a 1-d array and returns that average. Call this function multiple times to find averages across all rows and columns.Store each student’s quiz grades in an array called st_ave.Also store average of each quiz across all 4 students in another array called quiz_ave.Print all the information in a format that resembles the gray boxes below.
C++The program asks for the number n. Next, we enter n numbers and store all entered numbers into an array. You need to input only two "zero" numbers.The program should display the sum of all numbers that are located between zeros.Input:106 19 0 -3 4 8 0-6 9 5Output: 9Note: Numbers between two zeros are -3, 4 and 8. And their sum equal to -3+4+8=12Greate a function for this task in this way:int sum_between_zeros(int a[], int size){}
c++ Below, write the code of the program that calls the desired functions in the main function and performs the desired operations. a) random (random number range should be set to be in the range of 5-15) 10 an integer with an element produces numbers and transfers them to an array called array A and displays them enter a function that prints. b) then this sequence takes the arithmetic mean of the elements of the sequence A,round the found average value to the nearest large integer and return it to variable A.enter a function that assigns and prints the variable A on the screen. c) then write a function that finds the factorial of the variable A value and assigns it to factorial A and prints it on the screen
5. Write a function which will find the average of all elements of an array of integers. Pass an array and a dimension (the number of elements), and return the value of the average as a float ( the return value). Test this function in the main program with the array: 5, 7, 3, 5, 6, 4.
