Question

Write the following 7 C++ files (all function definitions must be in the cpp files): Shape h declaration of Shape class Shape.cpp definitions of Shape class functions Circle h declaration of Circle class, publicly inherited from Shape Circle.cpp definitions of Circle class functions Rectangle. h declaration of Rectangle class, publicly inherited from Shape Rectangle.cpp definitions of Rectangle class functions Prog12 cpp main program to use the classes Shape class contains: Private Data: x coordinate integer y coordinate integer shape type string Functions: default constructor-assign "unknown shape" to type variable and 0,0 as the location. constructor that receives shape type, x, and y values and sets the private data fields set for location receives both x and y values and sets the private data fields (any integer value will be allowed) print writes out the shape type and location as shape type "at" (x,y) format. Ex: 'Circle at (23,75) or "Square at 12,460' Circle class nherited publicly from Shape contains Private Data: radius a positive double Functions: default constructor stores 1.0 into radius and sends "Circle" and 0,0 to the parent constructor constructor that receives x, y, and radius values. Send "Circle" and the x and y values to the parent constructor, and send the radius parameter value to the setRadius function. setRadius receives a double. If the double is 0, store it to radius data field, otherwise store 1.0 print use the parent class print function to write out "Circle at with the location, and then write out the radius, and the area. The output should look something like: "Circle at (23,750 with a radius of 2.0 has an area of 12.57". Show 2 decimal places of accuracy on the area value. calcArea calculates and returns the area of a circle with the radius from the private data field
