A function is declared virtual in base class when u are
having same functions in both base and derived classes and
you want to access both the functions with same function
call and its done using base class pointer.
e.g
class base
{
public:
void show(){cout<<"hi"};
};
class derived:pubic base
{
public:
void show(){cout<<"bye";}
};
int main()
{
base *ptr;
base b;
derived d;
ptr=&b;
ptr->show();//base class fn is called
ptr=&d;
ptr->show();//derived class fn is called
return 0;
}

#include #include #include #include void insert(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); insert(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void insert(char *items, int count) { register int a, b; char t; for(a=1; a < count; ++a) { t = items[a]; for(b=a-1; (b >= 0) && (t < items[b]); b--) items[b+1] = items[b]; items[b+1] = t; } } design an algorithm for Insertion Sort
