isupper

Teste si un élément figurant dans des paramètres régionaux est en majuscules.

template<Class CharType> 
   bool isupper( 
      CharType _Ch,  
      const locale& _Loc 
   )

Paramètres

• _Ch
  L'élément à tester.

• _Loc
  Les paramètres régionaux contenant l'élément à tester.

Valeur de retour

vrai si l'élément testé est un caractère de ponctuation majuscule ; faux dans le cas contraire.

Notes

La fonction de modèle retourne use_facet<ctype<CharType> >(_Loc).is(ctype<CharType>::upper, _Ch).

Exemple

// locale_isupper.cpp
// compile with: /EHsc
#include <locale>
#include <iostream>

using namespace std;

int main( )   
{
   locale loc ( "German_Germany" );
   bool result1 = isupper ( 'L', loc );
   bool result2 = isupper ( 'n', loc );
   bool result3 = isupper ( '3', loc );

   if ( result1 )
      cout << "The character 'L' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character 'L' in the locale is "
           << " not a uppercase character." << endl;

   if ( result2 )
      cout << "The character 'n' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character 'n' in the locale is "
           << " not a uppercase character." << endl;

   if ( result3 )
      cout << "The character '3' in the locale is "
           << "a uppercase character." << endl;
   else
      cout << "The character '3' in the locale is "
           << " not a uppercase character." << endl;
}
