fopen - Read file and save each line to variable in C -

i'm using fgetc , fopen read file in c. i'd first line in variable , second line in separate variable so:

f = fopen("textfile", "r");  if (!f) {    printf("error"); } else {    loop until end of newline , save entire line variable    1st line ==> line1    2nd line ==> line2 } 

so if textfile has:

hello world goodbye world 

line1 = "hello world" line2 = "goodbye world"

i'm thinking of looping until \n how should store characters? think simple question , maybe i'm missing something?

you want to:

i. use fgets() entire line, then

ii. store lines array of array of char.

char buf[0x1000]; size_t alloc_size = 4; size_t n = 0; char **lines = malloc(sizeof(*lines) * alloc_size); // todo: check null  while (fgets(buf, sizeof(buf), f) != null) {     if (++n > alloc_size) {         alloc_size *= 2;         char **tmp = realloc(lines, sizeof(*lines) * alloc_size);         if (tmp != null) {             lines = tmp;         } else {             free(lines);             break; // error         }          lines[n - 1] = strdup(buf);     } }
