  3. Topics • Functions: Define and call a function: 181-192 • Arrays: defines and manipulate an array: mix, max, map functions: 301-312. • Switch statement: See class notes • While loop: write a while loop for a given problem statement; classnotes • Random number generation: generate an integer random number in a given range. • Move objects using translate; pushMatrix and popMatrix. 133-135. B.Ramamurthy

  4. Sample questions • Ans: Rectangular box with class name, class attributes and functions (no need for full function definition) • Define a function with parameters and a return value? Example: Define a function rolldice that roll two dice and return the sum of the values of the dice. • How will you call this function and assign its value to a variable? • Define array and use it? Define an array and initialize it daily temperature for this week (assume some values). Use a for loop and array length function to sum up the elements and determine the average for the week. • Convert an if statement to a switch statement? We will discuss this on Monday. • Generate a random number in a given range? Use this in a while loop? Determine the sum of a random number until the sum becomes 100. Print all the random number inside the loop. We will discuss this Monday. • How will you move an object in Processing using its x and y coordinates? If you understand translate, pushMatrxi and popMatrix that will be fine too. Otherwise just use x and y and try moving it. B.Ramamurthy

  5. Format • One question per topic discussed above. Only 8 questions • Each question may have subsections • We will NOT penalize you for syntax errors, but all important elements should be there B.Ramamurthy

  6. How to study? Prepare? • Come prepared: there is no substitute for hard work • Review class notes; Review sample questions; • Understand project work and class work • Find ways to efficiently answer questions • Find ways to avoid silly mistakes • Create a mental checklist to make sure you have not missed anything important on the exam (like your name of the exam paper!) • Read the question paper and strategize on the order in which you will answer the questions • Build up competencies as you are reviewing the course material and not deficiencies… • Good luck.
