please create the following in C++

5. Any class you create must not have any public data members. Create the following classes: (a) [1 point] A point class to represent x and y coordinates of a point on the coordinate system. You can assume that x and y can only have integer values. Provide a get and a set function for each data member. Create a default constructor to initialize x and y to 0 . Create a parameter constructor to initialize x and y to user supplied integers. Test the point class by creating objects and using its public functions. (b) [1 point] A triangle class to represent a triangle on the integer coordinate system. Figure 1: Triangle ABC Refer to Figure 1 above. The data to represent this triangle consists of values for coordinates of A, B, C, and area and perimeter of the triangle. Create a parameter constructor to initialize the coordinates of points A, B, and C, when the user supplies
