In C and C++, as well as in many (all?) languages, a function can be called from more than one place in a program. That's the purpose of functions - to encapsulate pieces of code that are needed in more than one place in the program.
No. You can only have one main() function in c/c++.
It is not the function but the compiler or interpreter which interprets the code. When the program is compiled and run the compiler checks the entire code line by line to check which function is called. If you encounter polymorphism in other Object Oriented Languages it would be more clear how a function with same name and different arguments are called.
Basic structure of a C program is /* Documentation section */ /* Link section */ /* Definition section */ /* Global declaretion section */ /* Function section */ (return type) (function name) (arguments...) void main() { Declaration part Executable part (statements) } /* Sub-program section */ (return type) (function name 1) (arguments...) (return type) (function name 2) (arguments...) . . . (return type) (function name n) (arguments...)

overload
In order to make a large program more manageable, it is convenient to identify and isolate specific tasks that a program performs and to separate out those tasks into functions. These functions are used/invoked as needed by the main part of the program. They can also be invoked by other functions. Often a program will perform the same task in different parts of the program. Using a function to perform the task and invoking the function from the different parts of the program means that only one copy of the code is needed. This helps reduce the size of the program.

function is a self contained block or sub program of two or more statements which performs a special task when called.

No, it does not.

You should have tried before asking... of course it can be...
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 function is a piece of code that has no or more arguments, that returns no or one value. A program is code that implements the function int main(int argc, char** argv). As such, a function and a program are the same, but the program also includes compiler directives to "include" other things, such as standard headers, i.e. #include .
Assuming that the independent variable (often called "y") is along the vertical axis: to be a function, no vertical line may cross the graph in more than one place.
In any source-files, the function names must be unique. In any program (which might be created from multiple source-files), the public function names must be unique.
What function do you mean? Any function defined in a source file? Or any function used in a source file? Be more specific.
Yes And even in the same program!
In-line functions differ from normal functions by the way they are dealt with by the compiler. Normally, a function (or its code, more exactly) is stored once within the executable program. A call to this function then results in putting the parameters onto the stack and jumping to the start address of the function. When the function is finished, the stack is freed from the parameters and the program continues right after the point from where it has jumped to the function. For an in-line function, its code is stored at any place where it is called. This saves us from the administrative overhead (putting parameters etc. onto the stack and cleaning up at the end) and, thus, reduced computing time. On the other side it enlarges the eecutable.<br> This leads to some restrictions to inline-functions.
