Object Oriented Programming Concepts:
The use of Object Oriented (OO) design and Object Oriented Programming (OOP) are becoming increasingly popular. Thus, it is useful to have an introductory understanding of OOP and some of the
programming features of OO languages. You can develop OO software in any high level language, like
C or Pascal. However, newer languages such as Ada, C++, and F90 have enhanced features that make
OOP much more natural, practical, and maintainable. C++ appeared before F90 and currently, is probably the most popular OOP language, yet F90 was clearly designed to have almost all of the abilities of
C++ . However, rather than study the new standards many authors simply refer to the two decades old
F77 standard and declare that Fortran can not be used for OOP. Here we will overcome that misinformed
point of view.
