B6

CError: Cannot pass variable as inout

DError: Missing & when calling function

Step-by-Step Solution

Solution:

Step 1: Understand the function behavior
The function increments the value of the variable passed by 1 using an inout parameter.
Step 2: Trace the code execution
Variable count starts at 5, then increment(&count) increases it to 6, so print(count) outputs 6.
Final Answer:
6 -> Option B
Quick Check:
inout lets function modify original variable [OK]

Quick Trick: Inout parameters let functions change original variables [OK]
