Answer 1

Following is a simple C++ example to demonstrate the use of default arguments. We don't have to write 3 sum functions, onl

Answer 2

Explanation:

Let us understand what a required function is:

Python allows the user to create user-defined function with pre-defined characteristics. One such feature is the "required function". So it ensures whether all the parameters are passed, provided the user-defined function should follow the syntax and keywords similar to pre-defined function.

def requiredArg (str1,str2):

  print(str1,str2 )

#Driver code

requiredArg ("Hello","everyone")

The above is the very simple program to illustrate "Required arguments".

First the driver code is invoked, so the function requires 2 string arguments and it is passed.

Inside the function we are printing the 2 arguments.

Suppose I write the below driver code:

requiredArg("Hello")

The above line will through "missing 1 required positional argument" error because, the function has required argument, so it requires all the parameters to be passed.
