Strings

• a sequence of characters enclosed in double-quotes:
  • "Hello World!"
  • "\nRing the bell \07"
  • ""
  • "\t Column 1 \t Column 2"
  
  
  
• Implemented in C as an array of characters:

  char name[] = "Dr. Lee" /* An array, one character per element. */ char *name_2 = "SimonH" /* Similar, oft-used, different: individual characters of name_2 canNOT be changed...*/

  We have

  name[0] == 'D' name[5] == 'e', name[6] == 'e'

  and

  name[7] == '\0' /* the null character */

  
  
• N.B. The null character --- this is implied implicitly on initialisation as above.
