Classes and instance in same model

[asadasivam]

Hi, Can I model a class diagram with instance. Like if we choose to model for this code from cpp, can we implement both. I couldn't able to generate code by using both instances and class. Any guide regarding this.

`` The Circle class (All source codes in one file) (CircleAIO.cpp) /

include // using IO functions

include // using string

using namespace std;

class Circle { private: double radius; // Data member (Variable) string color; // Data member (Variable)

public: // Constructor with default values for data members Circle(double r = 1.0, string c = "red") { radius = r; color = c; }

double getRadius() { // Member function (Getter) return radius; }

string getColor() { // Member function (Getter) return color; }

double getArea() { // Member function return radiusradius3.1416; } }; // need to end the class declaration with a semi-colon

// Test driver function int main() { // Construct a Circle instance Circle c1(1.2, "blue"); cout << "Radius=" << c1.getRadius() << " Area=" << c1.getArea() << " Color=" << c1.getColor() << endl;

// Construct another Circle instance Circle c2(3.4); // default color cout << "Radius=" << c2.getRadius() << " Area=" << c2.getArea() << " Color=" << c2.getColor() << endl;

// Construct a Circle instance using default no-arg constructor Circle c3; // default radius and color cout << "Radius=" << c3.getRadius() << " Area=" << c3.getArea() << " Color=" << c3.getColor() << endl; return 0; }``
