1. Write a function printSomeStrings( char list[ ][80], int sizeOfList, int startindex, int stopindex); that will print the strings in the array list , beginning with the item at index startindex and ending with the item at index stopindex . Each item should be printed on a new line. If startindex is bigger than stopindex , nothing should be printed. If startindex is less than 0, printing should start at index 0. If stopindex is great than the last index of the list, then printing should stop at the last item of the list. Example: If list is 0 lion \ 0 1 tiger \ 0 2 bear \ 0 3 moose \ 0 4 rat \ 0 printSomeStrings(list,5, 1, 3) produces tiger bear moose printSomeStrings(list, 5, -3, 1) produces lion tiger 2
