Question

IN C++ PLEASE -------Add code to sort the bowlers. You have to sort their parallel data also. Print the sorted bowlers and all their info . You can use a bubble sort or a shell sort. Make sure to adjust your code depending on whether or not you put data starting in row zero or row one. Sort by Average across, lowest to highest. The highest average should then be on the last row.. When you sort the average, you also have to move the names and scores, this is the reason you can't use a built-in sort.
