C++ commonly used hashinclude header file summary

This article lists in detail C++ contains the name of the header file and function description, more suitable for beginners to understand, almost every C++ file at the beginning of the #include, but most people did not pay attention to the #include after what, the comparison of this article will help you understand C++ structure more or less.

# include < A deque > //STL double-ended queue container
# include < The exception > // exception handling class
# include < fstream > // file input/output
# include < The functional > //STL defines an operator (instead of an operator)
# include < limits > // defines maximum constants for various data types
# include < The list > //STL linear list container
# include < The map > //STL mapping container
# include < iomanip > // parameterize input/output

Readers can understand the Chinese interpretation, and in the C++ program development quickly remember them, for the convenience of future programming.
