1. Array Allocator Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…

In C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()

m05B C++ Please extend my code to do the following: Write a brand new driver program that does the following: Creates a circle object circleOne at (0,0):5. Creates a pointer c1Ptr to circleOne Creates a circle object circleTwo at (-2,-2): 10 Creates a pointer c2Ptr to circleTwo Use greaterThan to check if circleTwo is bigger than circleOne and display results Declare an array of pointers to circles- circlePointerArray Call a function with signature inputData(circlePointerArray, string filename) that reads data from a file called dataLab4.txt into the array The following h-k are done in this function Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method. Read the coordinates for the center and the radius from instream to create the circles Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message “File Open Error”…

Dynamic Array Functions XLOOKUP What is one characteristic of the XLOOKUP) function that makes it so flexible? OPTIONS: It can only take dynamic arrays as input It can be used to lookup data both vertically and horizontally It always returns a matrix of data It takes only one input parameter

ASSIGNMENT-4 1. You have to create a memory size calculator in the C language that inputs the number of elements and the datatype of an array and prints the memory size(in Bytes) occupied by the array. User will enter 'i' for integer datatype, 'b’ for Boolean, 'c' for char, 'f for float and print "Invalid data type" for any other input.

use c++ Programming language  Write a program that creates a two dimensional array initialized with test data.  Use any data type you wish .  The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal:  This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…

In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.
