Question

q4) which of the following is not like the others? *
a) \2\
b) str(2)
c) \1\ + \1\

Explanation:

Answer:

This question falls under the discipline of Natural Science, specifically Computer Science. Without knowing the context of what "like" means in terms of data - types or operations, it's hard to give a definite answer. But assuming we are talking about data - type differences in a programming language context, if we consider that "2" and "1" + "1" are strings and str(2) converts the integer 2 to a string, if we assume normal programming language behavior, if we consider the nature of how they are created or represented, if we assume the language is Python for example:
If we assume "like" means having the same origin or creation method, the answer is b) str(2) because "2" and "1" + "1" are literal strings while str(2) is a result of a function call that converts a non - string (integer) to a string.
