示例
// 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;
}
