STL Sample for the min_element FunctionLast reviewed: October 9, 1997Article ID: Q156619 |
The information in this article applies to:
SUMMARYThe sample code below illustrates how to use the min_element STL function in Visual C++.
MORE INFORMATION
Required Header
<algorithm> Prototype
template<class InputIterator> inline InputIterator min_element(InputIterator first, InputIterator last)NOTE: The class/parameter names in the prototype do not match the original version in the header file. Some have been modified to improve readability.
DescriptionThe min_element algorithm returns the location of the minimum element in the sequence [first, last). The non-predicate version of min_element uses operator< for comparisons.
