Can anyone help me?
I want to insert data before head.
example :
3 4 5
I want insert 2 before 3,,but I get an error in C++ program.
This is my script
void insert_before(int s)
{
Node *before=head;
if(before->next->Data!=s) { //Example. Data = 2 and s = 3 4 5
printf("\nERROR\n");
}
else {
new->next=before->next;
before->next=new;
}
}

I do not see where you create a new Node for the inserted data.
Show the definition of the Node.
