- (Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forward(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(Data processing) Write a program that uses an array declaration statement to initialize the following numbers in an array named slopes: 17.24, 25.63, 5.94, 33.92, 3.71, 32.84, 35.93, 18.24, and 6.92. Your program should locate and display the maximum and minimum values in the array.arrow_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(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.arrow_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
- C++ program Write a basketball program such that it implements a two-dimensional array for 5 players whose score is entered into the array. In the game of basketball, there are 5 players on a team, and each team plays a game consisting of four 12 minute quarters. Write a C++ program that assigns randomly the points scored for each player in each quarter and then displays them. The maximum number of points any player can possibly score in a quarter is 18. Therefore, you will need a to declare an array which stores the points scored per player per quarter or a total of 4X5 = 20 array elements. Once the points are displayed for each player per quarter, Have the program display the following: -Which players scored the most points in every particular quarter out of all quarters played -Which player scored the most…arrow_forward(Check test scores) The answers to a true-false test are as follows: T T F F T. Given a two-dimensional answer array, in which each row corresponds to the answers provided on one test, write a function that accepts the two-dimensional array and number of tests as parameters and returns a one-dimensional array containing the grades for each test. (Each question is worth 5 points so that the maximum possible grade is 25.) Test your function with the following data: int score = 0;arrow_forwardİN C PROGRAMMİNG Write a program that fills an integer array of size 1000 with random positive integers between 1 and 10. Assume that each element represents a different city and the integers stored in the array represent the number of golds in those cities. The program traverses over the array and collects the golds at each city, starting from a random position. When the program visits a certain city, all of the golds are collected, and the visited element of the array becomes 0 (no gold is left at that city.) The journey continues with the rule given below. If the position at the nth step is denoted by pn, and the number of golds at the city pn is denoted by gn, ??+1 ={|(?? +??) ???1000|, ?????2=0. |(?? − ??) ??? 1000|, ????? 2 = 1 The program continues visiting cities until the last three visited city has no gold. The program, at each visit, should print out the following information: • The current city index (pn). • The previous city index (pn-1). • The number of golds at the…arrow_forward
- C++ Rainfall Statistics Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and the highest and lowest temperatures for the year. Your program must consist of the following functions: Function getData: This function reads and stores data in the two- dimensional array. The program should verify that the user entered a number and that the high number is higher than the low number for a month. Function averageHigh: This function calculates and returns the aver- age high temperature for the year. Function averageLow: This function calculates and returns the average low temperature for the year. Function indexHighTemp: This function returns the index of the highest high temperature in the array. Function indexLowTemp: This function returns the index of the lowest low temperature in the array. These functions must all have the appropriate parameters.

Output: Mean and median household size.

The program should calculate and display the total weight loss for the year, the average monthly weight loss, and the months with the highest and lowest amounts. Input Validation: Do not accept negative numbers for monthly weight loss.arrow_forward
