Write a C++ program that: • Implements a class with three data members {sum (int), count (int), avg (float)}. Implement the following 3 member functions: The first function is a default constructor which initializes sum and count to zero. The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. The third function is named outmut which divides the sum over count and save it to avg then print the avg value). Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbers. (

In C++ Write the implementation (.cpp file) of the Counter class of the previous exercise.The full specification of the class is: A data member counter of type int. An data member named counterID of type int. A static int data member named nCounters which is initialized to 0. A constructor that takes an int argument and assigns its value to counter. It also adds one to the static variable nCounters and assigns the (new) value of nCounters to counterID. A function called increment that accepts no parameters and returns no value. increment adds one to the instance variable counter. A function called decrement that accepts no parameters and returns no value. decrement subtracts one from the counter. A function called getValue that accepts no parameters and returns an int. It returns the value of the instance variable counter. A function named getCounterID that accepts no parameters and returns an int. getCounterID returns the value of the data member counterID.

Game of Chess in C++ The objective of this assignment is to practice concepts related to inheritance, overriding, polymorphism, and abstract classes, to program the basics of a chess playing program. About: Chess is played on an 8 X 8 board where the initial placement of pieces. The white king is on e1, and the black king is on e8. Each chess piece can move in a specific way. Follow a simplified version. Most importantly, ignore an important rule in chess: Moving any piece in a way that puts your own king in check is illegal. Since we don't know what check means, for us a move is legal if the piece we are moving has an empty square to move to or can capture (replace) an opponent's piece (including their king). The king does not move at all. Nor can it castle the queen and knight can't move either. A pawn in the initial position may move one or two squares vertically forward to an empty square but cannot leap over any piece. Subsequently it can move only one square vertically forward…
