When operator function is declared as friend function?
Ideally, never. Friend functions should only be employed when a function (whether an operator overload or not) requires private access to a class, and it is not otherwise possible to provide a public interface without unduly undermining the class encapsulation. However, as programmer, it is your responsibility to ensure all friend functions adhere to the same class rules (which you yourself define) as do the members of your class, even though friends are not regarded as being members of the class. Ultimately, if you have no control over the friend function implementation, then you must not allow that function to be a friend of your class, as this will seriously undermine the encapsulation.
What is the declaration of the function to overload output operator inside class in c plus plus?
You can't overload the insertion operator (<<) from inside a class because the l-value must be an ostream object, but operator overloads implemented within classes always implicate the class instance itself as being the l-value. You must overload the insertion operator from outside of the class, like so: ostream& operator<<(ostream& lhs, const MyObject& rhs) { lhs << rhs.get_data(); return( lhs ); }
What is built-in function in c?
There are no built-in functions in C++. The definition of a built-in function is a function that does not need to be declared before it is used, but every function in C++ is user-defined and must be declared before it can be used. This includes functions provided by the C++ standard library which we declare by including the appropriate headers.Some articles mistakenly describe keywords such as while, switch and if as being built-in functions, however these are statements, not functions.C++ does provide several built-in operators, some of which look and behave very much like functions. For example, the built-in sizeof() operator can be used without any declaration and looks very much like a function, but its argument is not a value, it is a type name, and we cannot (easily) define a function that accepts a type name as an argument.The built-in typeid() operator also takes a type name argument, but it is often mistakenly regarded as being a user-defined function because we must include the C++ standard library header in order to use it. But that header is only required because the return value is a std::typeinfo object which is not a built-in data type.Unlike sizeof() and typeid(), the default global new and delete operators can be overridden with user-defined function operators, thus these are also mistakenly regarded as being built-in functions. However, only the overrides are functions because that's the only way to define an operator overload; the default global operators are built-in operators, not built-in functions.The semantic difference between a built-in operator and a built-in function may seem insignificant, however a real built-in function would be no different to a user-defined function other than the fact that it need not be declared before using it. But a user-defined function also has identity (a memory address) and we can pass that identity to other functions using a function pointer argument. But we cannot pass a built-in operator to a user-defined function because it has no identity, thus it cannot be regarded as being a built-in function.
What is operand in c plus plus?
An operand is the value that is being operated upon by an operator. For instance, the C++ increment operator (++) is a unary operator, which means it has only one operand, the variable that we wish to increment. This in the expression x++, x is the operand. The addition operator (+) is a binary operator and therefore has two operands. Thus in the expression x + y, x and y are the operands.

You are deleting a file from batch file Somehow the delete function not deleting some time?
Some files can be protected from being deleted either because they are important system files or belong to a person who protected it, so if you don't own the rights for the file/folder you wish to delete, the batch file will not delete and will just say "Access is Denied".
