Multi-function simply means more than one function. Every program must have at least one function, the main function (the entry point of the application), and although you can write an entire program using just this one function, breaking the program down into several smaller functions makes the code easier to read and maintain. A major advantage of multi-function programming is that functions can be called as often as required -- there is no need to write the same piece of code over and over again.
A procedure is simply a function in C++, therefore you define procedures just as you would any function. In some languages, a procedure is not a function as such, insofar as there is no return type. The C++ equivalent would therefore be a function that returns void.
-define class with necessary data member & member function. -create object of that class. -communication.
Yes.
There is no such term as "building function" in C++.
yes you looser
...a function call.
#define biggest (a) > (b) && (a) > (c) ? (a) : (b) > (c) ? (b) : (c)
yes,we can make function inline
Every C plus plus program that is a main program must have the function 'main'.
Control is returning to the caller of the function.
method
No. The standard does not define nor require a file concept.
