(C++ exercise) 5. Write a new Checkbook class that uses a dynamic array. Call the class a different name, since it will be different from the latest version that uses a static array. Start off with a dynamic array size of 2, made by the constructor. Every time the dynamic array becomes full and a new check has to be written, double the current size of the array. Write a doubleArray function for the class to do this, but place the function prototype in the private section, since you don’t want the client to call the function. Keep a pointer to the dynamic array in the private section. Write a getChecks function that will return a pointer to DataType (which is going to be the address of a dynamic array). Create a dynamic array in the getChecks function, copy the checks to it, and return the pointer to this dynamic array (so that you return its address). Do not return the pointer in the private section, because you don’t want the client to access (or possibly change) the saved array. Note that the dynamic array created in the getChecks function will not be destroyed at the end of the function; only the local pointer that points to it will. The client will receive the address of this dynamic array created in the getChecks function, however, and will be able to use the array. Write a comment which makes it clear that the client must free the dynamic array when the client is done with it (to prevent memory leak). Use a Check struct of your own design to test the class template.

    IN C++ ADD COMMENTS AS MUCH AS POSSIBLE Exercise 1: Duplicate the Arrays Suppose you are developing a program that works with arrays of integers, and you find that you frequently need to duplicate the arrays. Rather than rewriting the array-duplicating code each time you need it, you decide to write a function that accepts an array and its size as arguments. Creates a new array that is a copy of the argument array, and returns a pointer to the...

    USING C++: Write a function that given a 2D dynamic array of integers, will return the number of elements whose absolute value is smaller than a given value x. The function should take as arguments (in this order): a pointer to the array (i.e., 2D dynamic array) the number of rows the number of columns the given value The function should return the number of elements smaller in absolute value than epsilon E.g. if A={{0.2, -0.1, 3.4},{4.4, 0, -2}} and...

    Write C++ program (studentsGpa.cpp) uses dynamic allocation to create an array of strings. It asks the user to enter a number and based on the entered number it allocates the array size. Then based on that number it asks the user that many times to enter student’s names.

    must be done in C You will implement a function that matches one of the prototypes below. int maxArray(int size, int* arr); int maxArray(int size, int arr]); The first parameter is the number of elements in the array. The second parameter is an address to the beginning of an int array. In the body of the function, use a looping structure to identify and return the maximum (largest number) of the array. NOTE: The maximum of the same number, say...

    C++ problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector. This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have: A private member variable called dynamicArray that references a...
