INTERVIEW QUESTIONS C++ C++ BASICS DETAILS

Question: Difference between "C structure" and "C++ structure".

Answer: They are different. C struct can only contain data while C++ struct can contain functions and access limitation such as public, private etc just as a class (not totally the same as class!)

C structure:::
1)//single line comment about the programme.
2)headerfiles
3)macros,typedef...
4)global declarations
5)main()
6)statements.......


C++ STRUCTURE:::

1)/*multi line comments*/
2)headerfiles
3)typedef,inline functions
4)global variables.
5)class starts
6)acces specifiers
7)statements.....
8)class ends with an ;
9)main starts
10)statements.
11)main ends Source: CoolInterview.com

C-structure is based on collection of various data types in a single unit. It is open to all.
while C++ structure is " class " which contains all functions of c and additional features as data binding and data hiding. Source: CoolInterview.com

In "c" a structure binds different types of data under a same name.
like if we have to work with an employee's name of type char,his age of type int, his sex of type char or his address of type char then we can declare a structure named as employee so that we can use all its variable in the function.
with this ease "c" doesn't provide any security on using structure and any function can use its data.
the second limitation is that the structure in "c" allow only data or variable in it..there is no space for function.

These limitations are overcomed in "c++" structure whose name is "class".
the class gives us a facility to bind data and function which can use these data together in a new data type.
it covers the real world objects like school, car.......and many mores.
this also provides security on the data by its data hiding facility.........
It gives thee visibility label to us_public,protected and private,so tht we can block unwanted access of data.
