Question

#include <iostream>

class Question3

{

public:

virtual void Task1() = 0;

protected:

int x;

};

class Sub1: public Question3

{

public:

void get_data1() 

{

std::cout<<("Enter x: ");

std::cin >> x;

}

void Task1() 

{

if (x == 0) 

{

std::cout << "0 has no inverse number " << std::endl;

}

else

{

std::cout << 1.0/x<< std::endl;

}

}

};

int main()

{

Sub1 sub;

Question3* q = ⊂

sub.get_data1();

q->Task1();

return 0;

}

in this code. in the int main() section. q=c is there, what is that special character c.

it is not c right?
