std::sort

1.std::sort

sort的声明：

使用的时候没有注意 _Last，直接以array[4]代替了。。。找了半天错误。。。

 

template<class RandomAccessIterator>
  void sort(
      RandomAccessIterator _First,
      RandomAccessIterator _Last
   );
template<class RandomAccessIterator, class Pr>
   void sort(
      RandomAccessIterator _First,
      RandomAccessIterator _Last,
      BinaryPredicate _Comp
   );
//int array[4]

Parameters
_First

A random-access iterator addressing the position of the first element in the range to be sorted.

//起始位置 &array[0]

_Last

A random-access iterator addressing the position one past the final element in the range to be sorted.

//数组最后结束位置 &array[0] + sizeof(array)/sizeof(int)

_Comp

User-defined predicate function object that defines the comparison criterion to be satisfied by successive elements in the ordering. A binary predicate takes two arguments and returns true when satisfied and false when not satisfied.
