How do you move up a line?

Here's my code:

Code:

// Word per minute counter by Pinny Berlin (epb613@gmail.com)
// Do whatever you want with the code.

#include <stdio.h>
#include <time.h>
#include <termios.h> // for mygetch function
#include <unistd.h>  // for mygetch function

int mygetch( ) {

/* This function accepts and returns an inputed character immediatly (even before the user presses enter). Function written by VvV. */

  struct termios oldt,
                 newt;
  int            ch;
  tcgetattr( STDIN_FILENO, &oldt );
  newt = oldt;
  newt.c_lflag &= ~( ICANON | ECHO );
  tcsetattr( STDIN_FILENO, TCSANOW, &newt );
  ch = getchar();
  tcsetattr( STDIN_FILENO, TCSANOW, &oldt );
  return ch;
}

void secPause() {

// This function creates a ~1 second pause.

  time_t start, current;
  start = time(NULL);
  do {
    printf(" \b");
    current = time(NULL);
  } while (difftime(current, start) < 1);
}

int main ()
{

// The program counts how many words you type on average per minute.

  char c, buffer;
  time_t start, current;
  int spaces = 0;
  printf("\nStart typing in... ");
  secPause();
  printf("3... ");
  secPause();
  printf("2... ");
  secPause();
  printf ("1  NOW!\n---> ");

  start = time(NULL);

  do {
    c = mygetch(); // Inputs a single keystroke
    if (c == ' ') spaces++;
    printf("%c", c);
    printf("   Total words per minute: %3d!", 60 / difftime(current, start) * spaces);
    printf("\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b");
    current = time(NULL);
  } while (1);

  printf("\n");
  return 0;
}

Compiling this and run it (press ctrl-c to quit). You'll see that at the end of every line, the text "Total words per minute: 77" remains. '/b' goes back a space but it doesn't go back a line. How do you go back a line?

Thanks in advance.

P.S. Anyone know why my secPause funtion doesn't work out if I take out the printf line? I can't figure it out.

ty. Any idea about the secPause function?
