(Practice) Define an array named peopleTypes that can store a maximum of 50 integer valuesentered at the keyboard. Enter a series of 1s, 2s, 3s, and 4s into the array to represent people at a local school function; 1 represents an infant, 2 represents a child, 3 represents a teenager, and 4 represents an adult. No other integer value should be accepted as valid input, and data entry should stop when a negative value is entered. Your program should count the number of each 1, 2, 3, and 4 in the array and display a list of how many infants, children, teenagers, and adults were at the school function.
(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.
(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
(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) 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]
(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:
(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.
(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.
Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 20 and 50, inclusive. As each number is read, validate it and check its value. Numbers greater than 40 are to be stored as they are. Numbers that are less than or equal to 40 should be doubled and then stored. After reading all the values, display all the values which were stored.
Answer in C++ code please! (Duplicate Elimination with array) Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the array only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Provide for the 'worst case' in which all 20 numbers are different. Use the smallest possible array to solve this problem.
Use C#, and explain each step please. Use a one-dimensional array to solve the following problem: Write an app that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display only if it's not a duplicate of a number already read. Provide for the "worst case," in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values after the user inputs each new value.
(5)Select the correct way to declare a two-dimensional array.A. int data[3][2] = {{3,4,3},{5,-1,12}};B. int data[3][2] = {{3,4},{3,5},{-1,12}};C. Neither.D. Both.
