Q1: What will be the output of the following program?

#include<iostream.h> 
class Aptitude
{
    int x, y; 
    public:
    void show(void);
    void main(void);
};
void Aptitude::show(void)
{ 
    Aptitude b;
    b.x = 2;
    b.y = 4;
    cout<< x << ' ' << y;
}
void Aptitude::main(void)
{
    Aptitude b;
    b.x = 6; 
    b.y = 8;
    b.show();
}
int main(int argc, char *argv[])
{
    Aptitude run;
    run.main();
    return 0; 
}
