We are about to commence OC2 (running a week late) and I have given my students some algorithms to evaluate for revision. On one in particular I realised I made an error of logic when evaluatiing it myself and have now confused my self to point of frustration. It's the one below. It has two count loops which it uses to select data in an array but they both have identical conditions. As I am currently reading it values will never be passed to the second loop as the evaluation condition that ends the first loop will also end the second???? Scratches head......sure I'm failing to see obvious! Can anyone help pls<br><br>Brett<o:p></o:p></p><p style='margin-bottom:0cm;margin-bottom:.0001pt'><b><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>Question 12:</span></b><span lang=EN-US><o:p></o:p></span></p><p style='margin-bottom:0cm;margin-bottom:.0001pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>The following diagram shows the contents of an array of records used for mixing colours.</span><span lang=EN-US><o:p></o:p></span></p><p style='margin-bottom:0cm;margin-bottom:.0001pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>The name of the array is ‘COLOUR’.</span><span lang=EN-US><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Garamond","serif"'>The algorithm below is used to calculate colour values, using an array.</span> <o:p></o:p></p><p style='margin-bottom:0cm;margin-bottom:.0001pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>BEGIN</span><span lang=EN-US><o:p></o:p></span></p><p style='margin-bottom:0cm;margin-bottom:.0001pt;text-indent:36.0pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>SET TOTAL TO 0</span><span lang=EN-US><o:p></o:p></span></p><p style='margin-bottom:0cm;margin-bottom:.0001pt;text-indent:36.0pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>SET COUNTER TO 1</span><span lang=EN-US><o:p></o:p></span></p><p style='margin-bottom:0cm;margin-bottom:.0001pt;text-indent:36.0pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>WHILE COUNTER < 4</span><span lang=EN-US><o:p></o:p></span></p><p style='mso-margin-top-alt:5.0pt;margin-right:0cm;margin-bottom:0cm;margin-left:36.0pt;margin-bottom:.0001pt;text-indent:36.0pt'><span lang=EN-US style='font-size:7.5pt;font-family:"Garamond","serif"'>TOTAL = TOTAL + COLOUR [COUNTER] .
