How can a called function determine the number of arguments that have been passed to it?
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.
How operator overloading differ from function overloading?
Function overloading is multiple definition with different signatures(the parameters should be different) for the same function. The parameter list have to be different in each definition. The compiler will not accept if the return type alone is changed. Operator overloading is defining a function for a particular operator. The operator loading function can not be overloaded through function overloading.
What is function in oop?
A function is a block of code that has a name and it has a property that it is reusable i.e. it can be executed from as many different points in a C Program as required.Function groups a number of program statements into a unit and gives it a name. This unit can be invoked from other parts of a program. A computer program cannot handle all the tasks by it self. Instead its requests other program like entities - called functions in C - to get its tasks done. A function is a self contained block of statements that perform a coherent task of same kindThe name of the function is unique in a C Program and is Global. It neams that a function can be accessed from any location with in a C Program. We pass information to the function called arguments specified when the function is called. And the function either returns some value to the point it was called from or returns nothing.We can divide a long C program into small blocks which can perform a certain task. A function is a self contained block of statements that perform a coherent task of same kind.Structure of a FunctionThere are two main parts of the function. The function header and the function body.int sum(int x, int y){int ans = 0; //holds the answer that will be returnedans = x + y; //calculate the sumreturn ans //return the answer}
What is the difference between virtual function and function overriding?
Virtual Functions and Pure Virtual Functions are relevant in the context of class inheritance.Unlike Virtual Functions, Pure Virtual Functions do not require a body. This implies that when a base class defining such a function is inherited, the derived class must implement that function. Furthermore, the base class becomes abstract; meaning you cannot create an instance of the base class even if a body is implemented for the function. You are expected to derive from abstract classes; only the derived classes that implement all the inherited Pure Virtual functions can be instantiated.Here are some examples of Virtual and Pure Virtual function signatures:- Virtual Function: E.g. virtual void myFunction();- Pure Virtual Function: E.g. virtual void myFunction() = 0;
Why javascript function name and variable name same?
Either a case of bad programming practise or probably the function calls itself.
