- (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=Farrow_forward(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 Voltsarrow_forward(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().arrow_forward
- (Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forwardThe range of a set of values is the difference between the highest value and the lowest value in the set. Write a C/C++ program that prompts the user to enter N integer values and stores it in an array. Calculate and display the range of the values, as well as the largest and smallest values in the set. TIP: you can declare an array of size N by declaring the array after the user enters a value for N!arrow_forwardq2 ) In an array A[10], the last element is defined with index ________. a.

Lucky Number Definition:● A lucky number is a number whose value is equal to the occurrence of that number in anarray.○ [2, 2, 3, 3] => 2● If there is more than one number whose value is equal to the occurrence of that numberin an array, then the lucky number will be the one with the maximum value among alllucky numbers.○ [1, 2, 2, 3, 3, 3, 4] => 3● If there is no number in an array whose value is equal to the occurrence of that numberin the array then the lucky number will be -1.○ [5] => -1Implement a function getLuckyNumber(numbers) that takes an array of positive integers asinput and returns the lucky number from the array.Test Cases:● getLuckyNumber([2, 2, 3, 3]) => 2● getLuckyNumber([1, 2, 2, 3, 3, 3, 4]) => 3● getLuckyNumber([5]) => -1getLuckyNumber(numbers){// function implementation// return number whose value is equal to the occurrence of the number in the array// e.g [2, 2, 3, 3] => lucky number = 2// in case there are multiple lucky numbers…arrow_forwardLottery Winners Directions A lottery ticket buyer purchases 10 tickets a week, always playing the same 10 5-digit “lucky” combinations. Write a program that initializes an array or a vector with these numbers and then lets the player enter this week’s winning 5-digit number. The program should perform a linear search through the list of the player’s numbers and report whether or not one of the tickets is a winner this week. Here are the numbers: 13579, 26791, 26792, 33445, 55555, 62483, 77777, 79422, 85647, 93121 Validate the input for the week's winning number. Ensure the input does not crash when entering a character or string value. Make sure to accept only positive numbers. Ask the user for the correct value each time they enter an incorrect one.arrow_forwardc++ A lottery ticket buyer purchases 10 tickets a week, always playing the same 10 5-digit “lucky” combinations.

The program should have an array of five integers named lottery and should generate a random number in the range of 0 through 9 for each element in the array. The user should enter five digits, which should be stored in an integer array named user. The program is to compare the corresponding elements in the two arrays and keep a count of the digits that match. For example, the following shows the lottery array and the user array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lottery array: 7 4 9 1 3 user array: 4 2 9 7 3 In C++ The program should display the random numbers stored in the lottery array and the number of matching digits. If all of the digits match, display a message proclaiming the user as a grand prize winner. Input Validation: Do not accept a negative value for lottery number. Also keep track of array size.arrow_forward
