Virtual Functions: Syntax

class person {

protected:

virtual char *print_sex(void) { cout << “I’m a generic person\n”; };

};

class female : person {

protected:

virtual char *print_sex(void) { cout << “I’m a female\n”; };

};

class male : person {

protected:

virtual char *print_sex(void) { cout << “I’m a male\n”; }

};

person *people[3];

people[0] = new person;

people[1] = new female;

people[2] = new male;

for (int i = 0; i < 3; i++)

people[i]->print_sex();

Without virtual, all three print statements will print “I’m a generic person”. With virtual, the three statements will report being generic, female, and male.
