Question

I would like to know what is wrong with the following C++ code. It crashes on Run.

#include <iostream.h>
#include <conio.h>
using namespace std;

class node
{
    public:
        int info;
        node *addr;

        node(){
            info = 0;
            addr = NULL;          
        }

        ~node(){}
};

void func(node *);


int main(void){   
    node *head;
    node b;

    b.info = 10;

    *head = b;

    func(head); 
    getch();
}

void func(node *obj){
    cout<<"i: "<<(*obj).info;
}

Answer 1

*head = b;

is not correct since head doesn’t point to anything

head = &b ;

should solve the problem
