Java How To Program (Early Objects)
- (Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.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_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
- (List maintenance) The following letters are stored in an alphabet array: B, J, K, M, S, and Z. Write and test a function named adlet(), which accepts the alphabet array and a new letter as arguments, and then inserts the new letter in the correct alphabetical order in the array.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(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward
- (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.arrow_forward(Data processing) The answers to a true-false test are as follows: T T F F T. Given a twodimensional 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 the maximum possible grade is 25.) Test your function with the following data: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
- (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):arrow_forward(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?arrow_forward(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forward
