Assuming that soap is an instance of the the Inventory class, which of the following below is a valid call to the setOnHand member function. setonHand (20); soap::setOnHand (20); soap.setOnHand (20); Inventory.setOnHand (20); The following program contains errors. Find as many as possible. class circle: { private double centerX; double center; double radius; public SetCenter (double, double); setRadius (double); }

Solution

a) cout<< ptr;

b) it will print 7;

c) cout<<iptr; will result in print of address of x in hexadecimal;

d) D) soap.setOnHand(20);

e)

erros;

correct example;

class circle

{

private:

double centerX;

double center;

double radius;

public:

void SetCenter(double,double);

void setRadius(double);

};
