Front functions such as vector::front(), list::front() and queue::front() return the first object in a container class. Not to be confused with begin() functions such as vector::begin() which return an iterator object which is typically used in iterative functions (loops) to traverse the objects within a container.
Of course they are used. Both stand-alone and class-member functions are used in C++.
Turn on the intellisense feature.
In C there are functions only, In Java methodsonly (static methods as well), in C++ both.
c language is the structure oriented language and c does not follows the object oriented paradigms . c++ obeys the all object oriented language characteristics ========== C++ is a set of extensions to the C language to allow some (not all) principles of object-oriented programming to be used. Originally, C++ was a front end pre-processor for C and C++ compilers will translate C language functions.
The only difference is that C does not use nor require prototypes. C++ does because all functions and types must at least be declared, if not defined, before they can be used.
Yes, there can be friend functions in C++.
No, they are functions. Operators are -> or ++or /=
Of course they are used. Both stand-alone and class-member functions are used in C++.
In C++, methods are simply class member functions.
One.
It should work without any special action.
Turn on the intellisense feature.
C++ built-in functions are those functions that are provided for you as part of the language itself, and includes all of the C standard library functions (all of which were inherited from C) and is expanded upon by the C++ standard template library. C++ implementors may provide additional functions that are platform-specific, however these are not considered built-in functions becuase C++ is a cross-platform language. These are best described as 3rd party functions. The functions you yourself write are known as user-defined functions.
Constant data and constant functions.
A singleton.
The C++ standard library contains all the pre-defined functions.
Put their names into the parameter-list.
