Finds the smallest element in a valarray.

Syntax

Type min( ) const;

Return Value

The minimum 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_min.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>

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

   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;
   for ( i = 2 ; i < 10 ; i += 3 )
      vaR [ i ] =  5 - i;

   cout << "The operand valarray is: ( ";
      for ( i = 0 ; i < 10 ; i++ )
         cout << vaR [ i ] << " ";
   cout << ")." << endl;

   MinValue = vaR.min ( );
   cout << "The smallest element in the valarray is: "
        << MinValue  << "." << endl;
}

The operand valarray is: ( 0 2 3 -3 8 0 -6 14 -3 -9 ).
The smallest element in the valarray is: -9.
