FreeRTOS - Memory Management

What will be the output of the following code snippet?

void *ptr = pvPortMalloc(50);
if(ptr != NULL) {
    vPortFree(ptr);
    printf("Memory freed\n");
} else {
    printf("Allocation failed\n");
}

AMemory freed

BAllocation failed

CCompilation error

DNo output

Step-by-Step Solution

Solution:

Step 1: Analyze memory allocation and check pointer
The code tries to allocate 50 bytes. If successful, ptr is not NULL.
Step 2: Free memory and print message
Since allocation likely succeeds, vPortFree(ptr); is called and "Memory freed" is printed.
Final Answer:
Memory freed -> Option A
Quick Check:
Successful allocation prints "Memory freed" [OK]

Quick Trick: Check ptr != NULL before freeing memory [OK]
