ispunct

測試項目置於地區設定是否為標點符號。

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

參數

• _Ch
  項目要測試的。

• _Loc
  包含項目的地區設定要測試。

傳回值

true ，如果測試的是標點符號; false 。

備註

樣板函式會傳回 use_facet<ctype<_Loc(CharType> >)。是(ctype<CharType>::punct， _Ch)。

範例

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

using namespace std;

int main( )   
{
   locale loc ( "German_Germany" );
   bool result1 = ispunct ( 'L', loc );
   bool result2 = ispunct ( ';', loc );
   bool result3 = ispunct ( '*', loc );

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

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

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

Output

The character 'L' in the locale is  not a punctuation character.
The character ';' in the locale is a punctuation character.
The character '*' in the locale is a punctuation character.
