Can we do overloading with default argument?

Can we do overloading with default argument?

Default arguments are a convenience, as function overloading is a convenience. Both features allow you to use a single function name in different situations. The difference is that with default arguments the compiler is substituting arguments when you don’t want to put them in yourself.

Which of the operators can have default arguments when they are overloaded?

function call operator
Of the operators, only the function call operator and the operator new can have default arguments when they are overloaded.

How are default arguments passed to functions?

A default argument is a value provided in a function declaration that is automatically assigned by the compiler if the caller of the function doesn’t provide a value for the argument with a default value. When Function overloading is done along with default values. Then we need to make sure it will not be ambiguous.

What happens when you overload functions?

Overloaded functions enable you to supply different semantics for a function, depending on the types and number of arguments. For example, a print function that takes a std::string argument might perform very different tasks than one that takes an argument of type double .

What do you understand by default arguments in function explain with suitable example?

The default arguments are used when you provide no arguments or only few arguments while calling a function. If you pass only one argument like this: sum(80) then the result would be 100, using the passed argument 80 as first value and 20 taken from the default argument.

Which of the following is used in function overloading and function with default argument?

Which of the following feature is used in function overloading and function with default argument? Explanation: Both of the above types allows a function overloading which is the basic concept of Polymorphism.

When we define the default values for a function?

Explanation: Default values for a function is defined when the function is declared inside a program.

What is operator overloading how many arguments are required to overload a binary operator if operator function is a member of a class or friend of a class?

Binary operators declared as member functions take one argument; if declared as global functions, they take two arguments. If an operator can be used as either a unary or a binary operator (&, *, +, and -), you can overload each use separately. Overloaded operators cannot have default arguments.

Which of the following feature is used in function overloading and function with default argument?

What are the advantages of default arguments?

Using default arguments gives the following advantages:

  • reduces the listing of the program code by avoiding writing unnecessary functions that perform the same work only with other values of the arguments;
  • provides a simple, natural and effective programming style;

Why function overloading is important?

The function overloading feature is used to improve the readability of the code. It is used so that the programmer does not have to remember various function names. If any class has multiple functions with different parameters having the same name, they are said to be overloaded.

What is function overloading give suitable example for function overloading?

Function overloading is a C++ programming feature that allows us to have more than one function having same name but different parameter list, when I say parameter list, it means the data type and sequence of the parameters, for example the parameters list of a function myfuncn(int a, float b) is (int, float) which is …
