    structs and linked lists

    For an assignment I have to create a linked list.
    I have to read from an input file and save the contents to a linked list.
    But before that I want to ask for advice which approach would be wiser.
    The Input file looks something like this.
    Jake 21
    Mark 22
    King 34
    William 25 and so on.. in total I have 26 names with age.

    I have looked up linked lists.

    |data |217| | data |218| |data |NULL|

    So I have data with the adress of the next nodes.
    My guess is that for each nodes I store name and age.
    However I have 26 Names in the input file should I create 26 nodes?
    Would that make any sense or am I completely on the wrong track?

    I apologize if this is a stupid question, but I have been looking for tips on the internet for hours and I can't seem to find a sensible approach.

    I have just come up with a soloution ignore this post sry

    I hope that the solution you came up with involves:
    • A struct type to model the data consisting of name and age.
    • A struct type to model the node that contains the data struct and the next pointer
    • Especially if your linked list has both head and tail: a struct type to model the entire linked list

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
