valarray::max
Finds the largest element in a valarray.
Type max( ) const;
Return Value
The maximum value of the elements in the operand valarray.
Remarks
The member function compares values by applying operator< or operator> between pairs of elements of class Type, for which operators must be provided for the element Type.
Example
// valarray_max.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>
int main( )
{
using namespace std;
int i, MaxValue;
valarray<int> vaR ( 10 );
for ( i = 0 ; i < 10 ; i += 3 )
vaR [ i ] = i;
for ( i = 1 ; i < 10 ; i += 3 )
vaR [ i ] = 2*i - 1;
for ( i = 2 ; i < 10 ; i += 3 )
vaR [ i ] = 10 - i;
cout << "The operand valarray is: ( ";
for (i = 0 ; i < 10 ; i++ )
cout << vaR [ i ] << " ";
cout << ")." << endl;
MaxValue = vaR.max ( );
cout << "The largest element in the valarray is: "
<< MaxValue << "." << endl;
}
The operand valarray is: ( 0 1 8 3 7 5 6 13 2 9 ). The largest element in the valarray is: 13.
