Learning New C++ Standards - for loop simplification
Usually for loop takes a counter to iterate through the elements. For that you have to initialize a counter, check whether the counter is less than the total element count, then take element from the container and use use it and increment counter.
Eg:
for (int i = 0; i < myList.size(); ++i)
{
myList[i];
C++ 11 made this thing simpler as follows
for (int elem : myList)
{
++elem;
This is called "range-based for" loop. The element type can be reference too. C-style arrays, standard library containers and any containers which has begin(), end() methods which return iterator can be used in this form.
