Object oriented data/code

Classes combine data with function(=methods) that operate on this data

• member (data): should be private.
• methods operate on these members (also with additional in/output parameters)
• principle of encapsulation:
• the storage of member/data should be hidden from the user.
• only the action (=method) of them is seen from the outside.
• Basic methods:
• constructors: parameter constructors
• destructor
• Example: intro_crsmatrix(tar, doc).
• 
  

Templates

• write one code for many data types.
• only header file is needed.
• compiler creates functions for all required data types.
• function templates, class templates

STL (Standard Template Library)

• Container, algorithms, iterators
• iterators are the link between containers and algorithms on them.
• Containers (e.g.):
• vector<T>
• list<T>
• Algorithms (e.g.):
• sort, unique, find, lower_limit,
• Methods on containers (e.g.):
• C.push_back()
• C.erase()
• C.insert()
