    strings

    how would i write a program that could read an unknown amount of lines from an external text file? where a string would read each line individually in a loop?

    using
    while(fgets(...))
    loop
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    have you read the fgets function description? It will return NULL when read fails - for example due to end-of-file condition. Thus while loop will end
