Question
What is the value of the following expression?
i = 1;
i < < 1 % 2;
a. 2
b. -2
c. 1
d. 0
Solution
The expression seems to be written in a C-like language, but it contains a syntax error. The "<<" operator is a bitwise shift operator, but there is a space between the two "<" symbols. If the expression is intended to be "i << 1 % 2", then the steps to evaluate it would be as follows:
- Evaluate the modulus operation: 1 % 2 = 1
- Perform the left shift operation: i << 1 = 2 (since i = 1)
So, the value of the expression "i << 1 % 2" is 2. Therefore, the correct answer is:
a. 2
