Nonpredicate Version of max_element

Illustrates how to use the nonpredicate version of the max_element Standard Template Library (STL) function in Visual C++.

template<class InputIterator>  
   inline InputIterator max_element( 
      InputIterator First, 
      InputIterator Last 
   )

Remarks

The max_element algorithm returns the location of the maximum element in the sequence [First, Last). The nonpredicate version of max_element uses operator< for comparisons.

Example

// max_element.cpp
// compile with: /EHsc
// Illustrates how to use the max_element function.
//
// Functions:
//    max_element : Return the maximum element within a range.

// disable warning C4786: symbol greater than 255 character,

#include <iostream>

using namespace std;


int main()
{
    const int VECTOR_SIZE = 8 ;

    // Define a template class vector of int
    typedef vector<int > IntVector ;

    //Define an iterator for template class vector of strings
    typedef IntVector::iterator IntVectorIt ;

    IntVector Numbers(VECTOR_SIZE) ;

    IntVectorIt start, end, it, location ;

    // Initialize vector Numbers
    Numbers[0] = 4 ;
    Numbers[1] = 10;
    Numbers[2] = 10 ;
    Numbers[3] = 30 ;
    Numbers[4] = 69 ;
    Numbers[5] = 70 ;
    Numbers[6] = 96 ;
    Numbers[7] = 100;

    start = Numbers.begin() ;   // location of first
                                // element of Numbers

    end = Numbers.end() ;       // one past the location
                                // last element of Numbers

    // print content of Numbers
    cout << "Numbers { " ;
    for(it = start; it != end; it++)
        cout << *it << " " ;
    cout << " }\n" << endl ;

    // return the maximum element in the Numbers
    location = max_element(start, end) ;

    cout << "The maximum element in Numbers is: "
        << *location << endl ;
}

Output

Numbers { 4 10 10 30 69 70 96 100  }

The maximum element in Numbers is: 100
