Hello all,

So I have this data input file...

Now, I having difficulties trying to read each line from my input file by using getline.

Another concerns, I'm trying to figure out which string function that I would need to use in order to go through each data that is separated by the white spaces. And then convert it to the correct type.


Here's what I have so far...

int main( int argc, char *argv[] )
{
        int choice, choice_1 = 0;
        int index, i, j, bytes_read, end_of_file = 0;
        FILE *exercisefile;
        struct program exercise = {NULL}; //Declaring a struct of programs called exercise
        struct program *head, *new, *current, *previous; //Declaring pointers




                my_string = (char *) malloc (struct program + 1);                        
                bytes_read = getline (&my_string, &struct programs, exercisefile);        
                puts (my_string);

You'll need to write your own getline. There's no such standard function. You probably want something like fgets, or to write your own using something like fgetc.

[elwad]

i think he has written it as a function right ?

[quzah]

He's written a call to that function. But he hasn't actually defined that function anywhere in his code.

nvm i didnt see the subject of his question...

give us ur full code. If this is ur full code then it should have a return 0 and a ending curly brace. as quzah already told there is no such function getline in the standard library, but u can always write ur own and use it as u wish.
