valarray::operator/=

由項目指定的valarray或項目型別的值除以運算元valarray項目。

valarray<Type>& operator/=(
   const valarray<Type>& _Right
);
valarray<Type>& operator/=(
   const Type& _Right
);

參數

• _Right
  項目型別的valarray或值與要分割valarray的運算元，項目，將valarray的運算元。

傳回值

項目是項目 _Right.除以的商數運算元valarray的valarray

範例

// valarray_op_ediv.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>

int main( )
{
   using namespace std;
   int i;

   valarray<double> vaL ( 6 ), vaR ( 6 );
   for ( i = 0 ; i < 6 ; i += 2 )
      vaL [ i ] =  100;
   for ( i = 1 ; i < 6 ; i += 2 )
      vaL [ i ] =  -100;
   for ( i = 0 ; i < 6 ; i++ )
      vaR [ i ] =  2*i;
   
   cout << "The initial valarray is: ( ";
      for (i = 0 ; i < 6 ; i++ )
         cout << vaL [ i ] << " ";
   cout << ")." << endl;

   cout << "The initial Right valarray is: ( ";
      for (i = 0 ; i < 6 ; i++ )
         cout << vaR [ i ] << " ";
   cout << ")." << endl;

   vaL /= vaR;
   cout << "The element-by-element result of "
        << "the quotient is the\n valarray: ( ";
      for (i = 0 ; i < 6 ; i++ )
         cout << vaL [ i ] << " ";
   cout << ")." << endl;
