Final answer:
The output of the given code snippet is 4.
Step-by-step explanation:
The output of the given code snippet is 4.
The code defines a function named func that takes two parameters, a and b. Inside the function, it uses the exponentiation operator (**), which calculates the power of a to itself.
When func(2) is called, it passes the value 2 as the argument for a and b which is not used in the function. As a result, the function returns 2 raised to the power of 2 which is 4.
