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 ).
