Strings, Arrays, and Pointers

• Reminder: There is no string type in C. Nevertheless, ...
•  
• A string is an array of characters with a terminating null byte ('\0').
• A string constant is an array of characters with a terminating null byte ('\0').
  Example: "This is a string."

• T

  h

  i

  s

  i

  s

  a

  s

  t

  r

  n

  g

  .

  \0

• A string constant is an expression that evaluates to the address of the first character in the string.
• Thus, a string constant is of type char *.
• Example: char * myString = "This is a string."
• The string.h functions take char * parameters.
  Examples: int strlen(const char * s), int strcmp(const char * s1, const char * s2)
