Merge two linked list

#1

my merge function is correct but my linked list is not taking inputs, please help

#2

Hello @WARHEAD,

Your builtN() function is logically incorrect.
Explanation:
After reading the element of the first linked list.
The element( stored in data) will be inserted to the linked list by passing it to InsertAtTail(head, data); (in the next iteration of the while loop).

Thereafter, cin>>data; will execute and read the size of the second linked list in the variable data.
Which is causing wrong output.

Modified Code:

void buildN(node*& head, int n)
{
int data;
//cin>>data;
while(n!=0)
{
cin>>data;
InsertAtTail(head, data);
//cin>>data;
n–;
}
}

Hope, this would help.
Give a like if you are satisfied.
