SUMMARY

(1) A class in C++ is similar to structure

in C. Using class or structure, a pro-

grammer can merge one or more dissim-

ilar data types and a new custom data

type can be created.

(2) In C++, classes and structures contain

member variables and member func-

tions in their declarations with pri-

vate and public access blocks that

restrict the unauthorized use. The de-

fined classes and structures further can

be used as custom data type in the pro-

gram to declare objects. ...
