How is an array stored in main memory? How is a linked list stored in main memory? What are their comparative advantages and disadvantages? Give examples of data that would be best stored as an array and as a linked list.
(Data processing) Construct a three-dimensional weather array for a two-week time period. Include this array in a C++ program that displays the temperatures correctly in response to any of the following user requests: • Any day’s high and low temperatures • Average high and low temperatures for a given month • Month and day with the highest temperature • Month and day with the lowest temperature
(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:
The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
(Practice) Write a C++ program that adds equivalent elements of the two-dimensional arrays named first and second. Both arrays should have two rows and three columns. For example, element [1][2] of the resulting array should be the sum of first [1][2]andsecond[1][2]. The first and second arrays should be initialized as follows: first second 16 18 23 24 52 77 54 9111 16 19 59
(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.
(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().
