• CPL – Combined Programming Language (1960s, University of Cambridge,
University of London)
• BCPL – Basic Combined Programming Language (1966, Martin Richards, language
for writing compilers)
• B (Dennis Ritchie, Bell Labs, 1969)
• C (Dennis Ritchie, Bell Labs, early 1970s, general purpose)
• C++ (Stroustrup, Bell Labs, 1983, C with objects)
• C++/CLI (Microsoft, 2005, “Managed” ECMA C++ Standard)

Why C++?
• C++ is General purpose programming
language
• Mid level language: Combination of both high
level language and low level language

Whats Needed
• It is a way to make programs more
comprehensive
• Code
– Each function has a clearly defined purpose and a
clearly defined interface to other parts of program
– Module: Grouping of a number of functions together
• Variables
– Global data: The one that is accessible to all the
functions
– Local Data: the one that is accessible only to its own
confined block

7. G
Object oriented programming
• Combine data + functions into a single unit
that operate on that data; such a unit is called
an object/Thing
– data + functions  object/Thing
• Object functions: Provide only way to access
its data; if you want to read a data item you
only need to access its function;
