FreeRTOS - Design Patterns for RTOS

Which of the following is the correct way to check a shutdown flag inside a FreeRTOS task loop?

Aif (shutdownFlag == true) { /* cleanup */ }

Bif shutdownFlag = true { /* cleanup */ }

Cif (shutdownFlag = true) { /* cleanup */ }

Dif shutdownFlag == true then { /* cleanup */ }

Step-by-Step Solution

Solution:

Step 1: Review correct C syntax for conditionals
Conditions require parentheses and double equals for comparison.
Step 2: Identify syntax errors in options
"if (shutdownFlag == true) { /* cleanup */ }" uses correct syntax. The others have errors: missing parentheses around the condition, using single '=' (assignment) instead of '==' (comparison), or invalid keywords like 'then'.
Final Answer:
if (shutdownFlag == true) { /* cleanup */ } -> Option A
Quick Check:
Correct conditional syntax = if (shutdownFlag == true) { /* cleanup */ } [OK]

Quick Trick: Use '==' for comparison inside parentheses [OK]
