CStringT::operator < 

Determines whether the string on the left side of the operator is less than the string on the right side.


friend bool operator<(
   const CStringT& str1,
   const CStringT& str2
) throw();
friend bool operator<(
   const CStringT& str1
   PCXSTR psz2
) throw();
friend bool operator<(
   PCXSTR psz1
   const CStringT& str2
) throw();

Parameters

str1

A CStringT for comparison.

str2

A CStringT for comparison.

psz1

A pointer to a null-terminated string for comparison.

psz2

A pointer to a null-terminated string for comparison.

A lexicographical comparison between strings, character by character until:

  • It finds two corresponding characters unequal, and the result of their comparison is taken as the result of the comparison between the strings.

  • It finds no inequalities, but one string has more characters than the other, and the shorter string is considered less than the longer string.

  • It finds no inequalities and finds that the strings have the same number of characters, and so the strings are equal.

//typedef CStringT< TCHAR, StrTraitATL< TCHAR > > CAtlString;
CAtlString s1("cat"), s2("cats"), s3("dogs");

_ASSERT(s1 < "dog");
_ASSERT(s1 < "cats");
_ASSERT(s2 < "cats and dogs");
_ASSERT(s2 < s3);
