The values of first and second as a result of executing the code segment are (c) first = 200 and second = 100
How to determine the value of the variables?From the code segments, we have the following assignment operations
first = 100 and second = 200
The variable first is assigned to variable temp.
So, we have:
temp = first = 100
The variable temp is assigned to variable second
So, we have:
second = temp = 100
Lastly, the variable second is assigned to variable first
first = 200
Hence, the values of first and second as a result of executing the code segment are (c) first = 200 and second = 100
