DMP - Chapter 4

Character Strings and Formatted I/O

• char Arrays and NULL (\0) character
• String constants
• strlen()
• Preprocessor directives (e.g. #include, #define) and constants
• #if 0, #endif
• <stdio.h> and "local.h"
• Conversion specifiers: %i %p %s
• Modifers (flag, digits)

  	
   -		left-justified, e.g. %-20s
  	
   +		plus or minus sign
  	
   space		leading space
  	
   #		alternative form
  	
   0		leading zeros
  	
   x.y		Minimum width, precision (min. # of digits)
  	
  		%s max number of characters
  	

#include <stdio.h>
#define DAYS 365
#define RENT 1234.56
#define AGE  31
#define BLURGB "Digtal Music"

	printf("/%d/\n", DAYS);

	printf("/%+4.2f/\n", RENT);
	printf("/%010.2f/\n", RENT);

	printf("%x %X %#x %#X\n", AGE, AGE, AGE, AGE);
	printf("**%+d**% d**%+d**% d\n", AGE, AGE, -AGE, -AGE);
	printf("**%5d**%5.3d**%05d**%05.3d**\n", AGE, AGE, AGE, AGE);

	printf("/%2s/\n", BLURB);
	printf("/%12s/\n", BLURB);
	printf("/%12.5s/\n", BLURB);
	printf("/%-12.5s/\n", BLURB);
	printf("/%  12s/\n", BLURB);
