Algol language family
Algol - AlgolW, Pascal, Modula2, Ada, Oberon, ... - CPL, BCPL, B, C C++ - Simula67 Java Eiffel - Algol68 Algol, 1960, initially conceived of as language for defining mathematical algorithms; implementations appeared by 1962 AlgolW (~1968), Pascal (~1970), Modula2 (~1978), Oberon (~1980s) N. Wirths family of languages primarily aimed at teaching programming

Algol language family
Algol - AlgolW, Pascal, Modula2, Ada, Oberon, ... - CPL, BCPL, B, C C++ - Simula67 Java Eiffel - Algol68 CPL overambitious Combined programing Language proposal (early 1960s) with Algol like features and some business data processing features (akin to IBMs PL/1) BCPL tiny subset of CPL, easily compiled to efficient computer code, aimed genuinely at systems programming tasks (op.



sys, utilities like editors, etc) C reworked BCPL

All languages in family have strong similarities
Basic build in ( yokelish) data types Similar expressions Similar flow control indoors a function
Sequence Selection Iteration

Data types
A fewer built in (primitive) types, everything
else will be an instance of a class
Unlike C++, you cant make your classes offshoot class types comparable in all respects to these built in types.

Built in types (aka primitive types)
integer arithmetic characters real arithmetic boolean

Similar function call mechanisms at once youve learnt one, you have good basis for switching to using another

integer types
C/C++ programs had portability problems related to integer types --- the number commence handled by a specific type is not delimitate in the standard! (Reason? This allows compiler writer to optimize code to suit capabilities of...If you want to get a full essay, ordain it on our website: Orderessay
