A counter variable is normally used in a program to keep track of the current count value.Create your own counter data type which is able to perform common counter operations such as increment (by one) the counter value and decrement (by one) the counter value. It is also able to set the counter to a specific value and to retrieve the counter value. The minimum value the counter can attain is zero, while the maximum value attained is stored in attribute maxValue. The class should have the following private members (attributes): (first picture) In the main program, test the workablity of your member functions by first setting an initial value to the counter. Display this value before proceeding. Then test other functions by randomly incrementing and decrementing the object’s value. Be sure to keep track of your actions. At the same time you should also make sure that your minimum value should not be less than zero. Once this is reached you will not be allowed to do further decrements.…

IN C++ Write code that: creates 3 integer values - one can be set to 0, the other two should NOT multiples of one another (for example 3 and 6, or 2 and 8) take you largest value and perform a modulus operation using the smaller (non zero) value as the divisor print out the result. create an alias for the string type call the alias "name" then create an instance of the "name" class and assign it a value using an appropriate cout statement - print out the value Please screenshot your input and output, as the format tends to get messed up. Thank you!

Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name.  The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…
