char_traits::eq_int_type

Comprueba si dos caracteres representados como s de int_typeson iguales o no.

static bool eq_int_type(
   const int_type& _Ch1,
   const int_type& _Ch2
);

Parámetros

• _Ch1
  El primero de los dos caracteres que se van a comprobar de igualdad como s de int_type.

• _Ch2
  El segundo de los dos caracteres que se van a comprobar de igualdad como s de int_type.

Valor devuelto

TRUE si el primer carácter es igual al segundo carácter; si no Falso.

Ejemplo

// char_traits_eq_int_type.cpp
// compile with: /EHsc
#include <string>
#include <iostream>

int main( )
{
   using namespace std;

   char_traits<char>::char_type ch1 =  'x';
   char_traits<char>::char_type ch2 =  'y';
   char_traits<char>::char_type ch3 =  'x';

   // Converting from char_type to int_type
   char_traits<char>::int_type int1, int2 , int3;
   int1 =char_traits<char>:: to_int_type ( ch1 );
   int2 =char_traits<char>:: to_int_type ( ch2 );
   int3 =char_traits<char>:: to_int_type ( ch3 );

   cout << "The char_types and corresponding int_types are:"
        << "\n    ch1 = " << ch1 << " corresponding to int1 = "
        << int1 << "."
        << "\n    ch2 = " << ch2 << " corresponding to int1 = "
        << int2 << "."
        << "\n    ch3 = " << ch3 << " corresponding to int1 = "
        << int3 << "." << endl << endl;

   // Testing for equality of int_type representations
   bool b1 = char_traits<char>::eq_int_type ( int1 , int2 );
   if ( b1 )
      cout << "The int_type representation of character ch1\n "
           << "is equal to the int_type representation of ch2."
           << endl;
   else
      cout << "The int_type representation of character ch1\n is "
           << "not equal to the int_type representation of ch2."
           << endl;

   // An equivalent and alternatively test procedure
   if ( int1 == int3 )
      cout << "The int_type representation of character ch1\n "
           << "is equal to the int_type representation of ch3."
           << endl;
   else
      cout << "The int_type representation of character ch1\n is "
           << "not equal to the int_type representation of ch3."
