6.5 Bowling program

At the beginning of your program printout the following:

1. Your name
2. CIS265 Louis Taber
3. Lab: 6.3: Bowling.

Your input data will be:

1. Players name
2. Number of pins knocked down with a ball.
3. -1 For end of game (next record new players name)
4. -2 For end of data file

For each game print out all ten frames. For each frame print out the following:

1. the number of pins knocked down for each ball.
2. If the frame was a strike or a spare.
3. The running score for the player.

Name:  John Doe
Frame  1:   Ball 1: 10   Ball 2: none  Strike    Score:   20
Frame  2:   Ball 1:  5   Ball 2:  5    Spare     Score:   36
Frame  3:   Ball 1:  6   Ball 2:  0              Score:   42

• More than 10 pins per frame. (In your error message printout the number of the errant frame, and count the frame as a total of zero pins.)
• More than 10 pins per ball. (In your error message printout the number of the errant frame, and count the frame as a total of zero pins.)
• Too many balls total. (Print error message, but score game using the balls needed.)
• Too few balls. (Use zero for all missing balls.)

The second one has lots of errors, to check your error handling code. It is available by anonymous FTP at
ftp://lt.tucson.az.us/pub/c/bwerror.dat.

An example program for reading the data file is available at:
ftp://lt.tucson.az.us/pub/c/read-bowling.c Here is the example program:

/* Louis Taber 3/26/2001
 *
 * --  Read bowling info
 *
 * Third example program for fscanf()
 * example of fscanf, errno, perror
 *                               */

#include <stdio.h>
#include <errno.h>

#define TRUE 1

int extern errno;

int main(int argc, char *argv[])
{
FILE *fp;
int score;
int balls;
char bowler[200];
char blanks[200];

if( argc == 1 )   /* No arguments -- use std input */
  {
  fp= stdin;
  }
else
  {
  if((fp = fopen( argv[1], "r")) == NULL)
    {
    printf(" Error(%d): %s\n", errno, strerror(errno)); 
    printf("%s(line %d): fopen error: %s\n",
           __FILE__, __LINE__,  argv[1]);
    return 1;
    }
  }


while( TRUE ) 
  {
  fgets(bowler, sizeof(bowler), fp);
  balls = 0;
  while( TRUE )
    {
    fscanf(fp, "%d", &score );
    if( score < 0 ) break;
    balls ++;
    printf(" %02d", score);
    }
  fgets(blanks, sizeof(blanks), fp);
  printf("\nballs: %4d  %s\n", balls, bowler);
  if( score == -2 ) break;
  }

fclose(fp);
return 0;
}

Mark your output two printouts and your listing with:

• Your name
• TABER CIS265
• Lab 6.5: Bowling
• The compiler and OS that you used.
