Final answer:
Additional local variables can be defined in the local declaration section of a function. True
Step-by-step explanation:
True. Additional local variables can be defined in the local declaration section of a function.
For example, in Python:
def calculate_sum(a, b):
# Local variable c
c = a + b
return c
In this code snippet, the variable c is defined within the function calculate_sum and can only be accessed within that function.
