- dynamically typed¶
A dynamically typed programming languages is one in which variables need not necessarily be defined before they are used, and can change during execution.
Header files are library files that contain a variety of useful definitions. They are imported into any C++ program by using the pre-processor #include statement.
Tells the preprocessor to treat the contents of a specified file as if they appear in the source program at the point where the directive appears.
An interpreter directly executes statements in a scripting language without requiring them to have been compiled into machine language.
- machine code¶
machine code is a computer program written in instructions that can be directly executed by a computer’s CPU.
- statically typed¶
A statically typed programming languages is one in which variables must be defined before they are used and cannot change during execution.
