Standard way to handle the encapsulated access to values
If it is you, you could put the sentinel value in both the first and last elements of the array - you could make it a number one larger than any other element in the array (or one smaller). You would then remember your max or min as you write every element, then pick your sentinel and then write it to both ends. Of course it would be easier to put the count of actual values in the first([0... A reference to the mapped value of the element with a key value equivalent to k. If the map object is const-qualified, the function returns a reference to const mapped_type . Otherwise, it returns a reference to mapped_type .

2011-08-13 · The first version returns a pair, with its member pair::first set to an iterator pointing to either the newly inserted element or to the element that already had its same value in the map. The pair::second element in the pair is set to true if a new element was inserted or false if an element with the same value existed....

Now imagine you have some big clients that give you a lot of work. To keep them happy, you decide to give them a reduction of 10 percent on the price per hour for orders that involve more than 100 hours of work. So, if the number of hours worked is
  • C++ Iterators. This is a quick This inserts the value in the place pointed to by the iterator. If you assign again, a new value will be inserted.
