Abstractions using Classes
This classNamehelps to group the data member and function member using available access specifiers. A classNamewill decide which data member is visible outside the world.
Abstraction using Header Files
Using the abstraction classNamein header files. Considering two header files math.h and pow(). This pow() is present inside the math.h header file and pass the number as arguments without using any algorithm according to the actually calculating power of numbers.
Abstraction using Access Specifiers
Abstraction is the main pillar of the object oriented programming. This access specifiers are used within the classNamemembers. Members can be declared as public, private and protected.
