  1. Selection Structure by Yonglei Tao

  2. Conditional Statements • Write an algorithm that asks the user for two numbers, and print the larger one. Get the values of a, b from user If the value of a is greater than the value of b then print “The larger number is ” & a Else print “The larger number is ” & b • Test 1:What does the program print if the user enter 10, 3? • Test 2:What does the program print if the user enter 2, 11?

  3. Example • Write an algorithm to compute the distance traveled and the average miles per gallon on a trip when given as input the number of gallons used and the starting and ending mileage readings on the odometer. get gallons, start, end distance = end – start mpg = distance / gallons print mpg if mpg > 25.0 then print “You are getting good gas mileage”

  4. Exercise • Write an algorithm that asks the user to enter three numbers, and computes and prints out the largest number
