Question

Consider this statement:

if (auto right_now = time(nullptr))
What is the scope of the variable right_now?
A) Limited to the if statement
B) Global scope
C) Limited to the function
D) Undefined

Answer 1

The variable 'right_now' in the given statement has a scope limited to the if statement itself and is not accessible outside of this block.

Step-by-step explanation:

The variable right_now in the statement if (auto right_now = time(nullptr)) has a scope that is limited to the if statement. This means the variable is created at the point of the if statement and can only be used within the if block. Once the if block is exited, right_now is destroyed, and it is not accessible outside this block.
