1.3 Standard Library (std)

• A set of commonly used functionality and data structures to build upon.
• It’s somtimes called the c++ standard template library (stl).
• It’s divided up into a number of separate files, and we make use of them by including them in any of out c++ programs.

Standard Library Organization

• All functionality used from the std will be part of the std namespace.
  • namespace allow us to avoid name conflicts for commonly used names.
• it can be imported into the global space with “using”:

  using std::cout
  

  • we can convert typing std cout into just typing cout.

Using uiuc namespace

• we have encapsulated the Cube class into the uiuc namespace.
• add curly brace, and we’re going to do that inside of both header and the cpp file.

Quiz

• A class can consist of multiple member data variables of different types, but each type must be specified when the class is defined.
• Even if the functions are declared in the class and implemented in a separate .cpp file, they are still part of the class.
• Namespaces allow different libraries to use the same label for a class or variable because they can each define a unique namespace to differentiate them when they are used together in a program.
