# Tutorial 10 --- - Assignment style feedback - Stacks and queues - Writing tests --- ### Style feedback Use more constants ```c= #define DRAW_LINE 1 #define FILL_RECTANGLE 2 #define CHANGE_SHADE 3 #define COPY_PASTE 4 #define ADDITIVE_BRUSH 5 ``` --- ### Style feedback More descriptive comments - Comments above the function prototypes describe what the function does - What do the inputs and outputs mean? - What assumptions are made? - Comment above the function definition about how the code works - How does your function work at a high-level? --- ### Style feedback Remove placeholder comments ```c= // ADD PROTOTYPES FOR YOUR FUNCTIONS HERE // TODO: Add your code here! ``` --- ### Style feedback Include a brief description of the program in the header comment --- ### Style feedback Write More functions! - Each function should only do 1 action - This generally means each function should be around 20-30 lines long. --- ### Stacks and Queues - FIFO - FILO --- ### Writing tests - Black box testing - Do not add functions to header - Use behavioural driven development (BDD) - GIVEN, WHEN, THEN - At least 1 test for each function --- ### General Revision Advice -
