    There's just 3 I/O functions you need to use here. fopen(), fclose(), and fgets(). Is your problem in understanding how to use these functions, or how to save the lines you read in with fgets()?

    well, best way to ready a line is using fgets fucntion. google fgets

    HINT: fgets(char *, no of bytes to be read, FILE *);
