• The string Member Functions
  string demo = "Monday morning";
  • length: int length()
demo.length() == 14
  • Substring: string substr(int pos, int len)
demo.substr(7,4) == "morn"
  • Contains: bool Contains(string s)
demo.Contains("day") == true
  • Find: int find(string s)
demo.find("y m") == 5
  • Lower Case: string Downcase()
demo.Downcase() == "monday morning"
  • Upper Case: string Upcase()
