When I compile the following code, I get compile error that " head does not name a type". Can someone explain what goes wrong ?
#include <iostream>
using namespace std;
/* Link list node */
struct node {
int val;
struct node* next;
node(int x)
{
this->val = x;
next = NULL;
}
};
struct node *head = new node(3);
head -> next = new node(4); // error: head does not name a type.
head -> next->next = new node(5); // error: head does not name a type.
void print(){
struct node* temp = head;
while (temp != NULL) {
cout << temp->val << " ";
temp = temp->next;
}
}
int main()
{
print();
return 0;
}
I cannot figure out why am i getting the error . Please someone help me out .
CodePudding user response:
Only declarations are allowed outside of functions. Expressions such as head->next = node(4)
need to be inside a function. You should move that code into main()
.
