Questions and Answers

What is the first step in an algorithm to find the average of two numbers?

  • Draw a flow chart
  • Calculate the difference
  • Read two numbers (correct)
  • Display the average
  • Which pseudo code statement would correctly represent swapping two numbers?

  • b = a + b; a = b - a; b = b - a;
  • temp = a; a = b; b = temp; (correct)
  • a = a - b; b = a + b;
  • a = b; b = a;
  • When organizing two numbers in descending order, which conditional statement would typically be used?

  • Always display a first
  • If a > b, then display a and b (correct)
  • If a < b, then display a and b
  • If a = b, then display both
