C-string

A string is a one-dimensional array of characters that can be terminated using a null character (‘\0’). The string or character array is used to manipulate the text such as words or sentences. The \0 (termination character) is the most important in the string as it is the only method to identify the end of the string. A string can be defined as a one-dimensional array of characters; whereas, an array of strings is a two-dimensional array of characters.

Question

Consider the following class definitions:
class A:
def
init
(self, par =
print("A", end = "")
print (par) if par is not None else print (2)
par = 2
class B (A):
def
init (self, par):
print ("B", end
")
y = A (par)
2):
=
What will be happen when the following statement is executed:
obj = B (4)
a) The code will print "B A 4"
b) The code will print "A 2 B A 4"
c) The code will generate an error
d) The code will print "B A 4 A 2"
