Answer 1

C switch statements require listing each value so one hundred case labels to use it here. Now, if you could use a/10 to have ten case labels, it might be fine.
switch ((a-1)/10) {
case 9:
printf("you are in top one percent");
break;
case 8:
case 7:
case 6:
case 5;
printf("you passed");
break;
case 4:
case 3:
case 2;
case 1:
case 0:
printf("you failed!");
break;
default:
printf("invalid score\n");
}
