min_element (STL Samples)

Visual Studio 2005

Illustrates how to use the min_element Standard Template Library (STL) function in Visual C++.

```
template<class InputIterator> inline
InputIterator min_element(
InputIterator First,
InputIterator Last
)
```

Remarks

Note

The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.

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

Example

```// min_element.cpp
// compile with: /EHsc
//
// Functions:
//    min_element - Return the minimum element within a range.

// disable warning C4786: symbol greater than 255 character,
// okay to ignore
#pragma warning(disable: 4786)

#include <iostream>
#include <algorithm>
#include <functional>
#include <vector>

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 minimum element in the Numbers
location = min_element(start, end) ;

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

Output

```Numbers { 4 10 10 30 69 70 96 100  }

The minimum element in Numbers is: 4```
