Lecture 16: October 30, 2019

Reading: C text, §11
Due: Homework #3, due November 8, 2019

  1. Greetings and felicitations!
  2. Arrays of strings
    1. int main(int argc, char *argv[]) (same as int main(int argc, char **argv))
    2. Example programs: echo.c, echo2.c
  3. Files
    1. Review files and file pointers — mention file descriptors as underlying mechanism
    2. Standard I/O library (stdio.h)
    3. Standard input, output, error (stdin, stdout, stderr)
    4. Opening, closing files (fopen, fclose)
  4. Reading, writing characters and lines
    1. Reading text data as lines (fgets, gets — do not use this!)
    2. Reading text data as characters (fgetc, getc, getchar, ungetc)
    3. Writing text data as lines (fputs, puts— latter adds a trailing newline)
    4. Writing text data as characters (fputc, putc, putchar)
  5. Reading, writing text data with a fixed format
    1. Reading in text data with a fixed format (fscanf, scanf)
    2. Outputting text data with a fixed format (fprintf, printf)
  6. Printing the contents of a file
    1. Simple copy (scopy.c)
    2. Using fputs (printfile1.c)
    3. Using putchar (printfile2.c)
    4. Using command-line arguments (printfile3.c)
  7. Binary file I/O
    1. Reading with fread
    2. Writing with fwrite
    3. Binary simple copy (sbcopy.c)
  8. Other useful stuff
    1. Test for end of file (feof, also EOF or NULL)
