-====== 2. C++ Language Reference ======
-Programming languages are a tool. While many modern programming languages are designed to be general purpose, some programming languages may be better suited to solve certain problems than others.
-===== When to use C++ =====
-===== When not to use C++ =====
-Unlike [[python3_ref|Python3]], it is difficult to argue that C++ is ever a //poor// choice for a contest problem. Well-written C++ is difficult to beat in terms of runtime efficiency. C++ boasts a well-established [[http://www.cplusplus.com/reference/|standard library]] of generics through templates, and many competitive programmers are versed in preprocessor macros that make C++ fell more like [[python3_ref|Python3]].
-However, for all the benefits of C++, well written [[python3_ref|Python3]] can be generated in fewer keystrokes than is possible in C++ or Java.((The standard "[[cpp_hello_world|Hello World!]]" in C++ takes can be accomplished in 107 keystrokes (not including editor commands) including the inclusion of ''iostream'', the use of ''namespace std'', typical whitespace/formatting, and C++ streams for output.)) This is due to both the terse syntax, and the lack of any required boilerplate in the most basic program.
