valarray::value_type

A type that represents the type of element stored in a valarray.

typedef Type value_type;

Remarks

The type is a synonym for the template parameter Type.

Example

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

int main( )
{
   using namespace std;
   int i;
   valarray<int> va ( 10 );
   for ( i = 0 ; i < 10 ; i += 2 )
      va [ i ] =  i;
   for ( i = 1 ; i < 10 ; i += 2 )
      va [ i ] =  -1;
   
   cout << "The initial operand valarray is:  ( ";
      for ( i = 0 ; i < 10 ; i++ )
         cout << va [ i ] << " ";
   cout << ")." << endl;

   // value_type declaration and initialization:
   valarray<int>::value_type Right = 10;

   cout << "The decalared value_type Right is: " 
           << Right << endl;
   va *= Right;
   cout << "The resulting valarray is:  ( ";
      for ( i = 0 ; i < 10 ; i++ )
         cout << va [ i ] << " ";
   cout << ")." << endl;
}

The initial operand valarray is:  ( 0 -1 2 -1 4 -1 6 -1 8 -1 ).
The decalared value_type Right is: 10
The resulting valarray is:  ( 0 -10 20 -10 40 -10 60 -10 80 -10 ).
