Computer Science · May / June 2017 · Paper 21 · Question 6

This flowchart inputs a range of temperatures in degrees Fahrenheit. As each temperature is input, it is compared with the previous highest temperature. If it is higher than the current highest, it replaces the previous highest temperature and then it is converted to degrees Celsius. For ease of calculation, the final step of the Fahrenheit to Celsius conversion has been approximated as division by 2. When –1 is entered, the input process stops and the highest temperature (in both Fahrenheit and Celsius) is output. Is TempF = -1? Is TempF > HighF? No No Yes Yes END HighF -100 HighC -100 INPUT TempF OUTPUT 'The highest temperature is, ', HighF, ' Fahrenheit, ', HighC, ' Celsius.' START HighF TempF HighC (TempF-32)/2 13 Complete the trace table for the input data: 68, 46, 50, 86, 65, 50, 40, 30, –1 HighF HighC TempF OUTPUT [5]
