Array:
- Array is a data structure that stores the sequence of similar type of data.
- It contains the sequence of data with common variable name and similar data type.
Syntax (in C++):
datatype arrayName[size] = {data1, data2,…,dataN};
Here,
datatype – Data type name
arrayName – Name of the array
size – It indicates the size of the array

Starting Out with Programming Logic and Design (4th Edition)
- (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(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(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forward
- Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not foundarrow_forwardYou can copy all elements of one array into one another with an assignment statement. True or Falsearrow_forwardProblem2: 2D Arrays Define a 2D array using Java code that takes from a teacher the total number of rows and the total number of columns. Then let the teacher fill the array by students IDs and courses marks for each student. And print the following: 1- Print the array. 2- Print the marks that are less than 50 (mark < 50)arrow_forward
- Problem1: 2D Arrays write a java code to Create a 3x3 2D array, fill it with numbers from the user, and check if the array is an hour glass shape or not.arrow_forwardDate Printer Write a program that reads a char array from the user containinga date in the form mm/dd/yyyy. It should print the date in the form March 12, 2014.arrow_forwardPrint true if the user-entered array contains, somewhere, three increasing adjacent. Programming language: Javaarrow_forward
- Monkey BusinessA local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 7 array, where each row represents a different monkey and each column represents a different day of the week. The monkeys are represented by integers 1, 2, and 3; the weekdays are "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday". The program should first prompt the user to input the data for each monkey, starting with "Sunday" for monkey #1, then monkeys #2 and #3, followed by "Monday" for monkey #1, then monkeys #2 and #3 and so on, through "Saturday". The program then creates a report that includes the following information, each properly labeled (see below): Average amount of food eaten per day by the whole family of monkeys. The least amount of food eaten during the week by any one monkey. The greatest amount of food eaten during the week by any…arrow_forwardC++ program This assignment is about array operations. Create an array with 1000 items and fill it with random numbers from the range of -100, 100 (including -100 and 100). Then, your program asks user to enter a number. The program keeps running until user enters a out-of-range (-100,100) number. An example run is given below. Enter a number: -4Frequency of -4: 54Enter a number: 4Frequency of 4: 15Enter a number: 35Frequency of 35: 8Enter a number: 43Frequency of 43: 2Enter a number: 101Bye...arrow_forwardprogramming used: javaarrow_forward
