Given this task function: void Task(void *pvParameters) { int *p = (int *)pvParameters; printf("Number: %d\n", *p); vTaskDelete(NULL); } If called with a pointer to an int variable holding 10, what is printed?

ACompilation error

BNumber: 0

CNumber: 10

DGarbage value

Step-by-Step Solution

Solution:

Step 1: Understand parameter usage
The task receives a void pointer, cast to int pointer, then dereferenced to print the int value.
Step 2: Given pointer points to int 10
Dereferencing prints 10 correctly.
Final Answer:
Number: 10 -> Option C
Quick Check:
Proper pointer cast and dereference = correct value [OK]

Quick Trick: Cast void* to correct pointer type before dereferencing [OK]

Common Mistakes:

Dereferencing void* directly
Casting void* to int instead of int*
Passing value instead of pointer
