Locale convenience function that determines whether a character is lower case


#include <locale>

namespace std {
  template <class charT> 
  bool islower(charT c, const locale& loc);


The islower() function returns true if the character passed as a parameter is lower case. Otherwise, the function returns false. The check is made using the ctype facet from the locale parameter.
