outputting certain array value
How would you go about menu option 3 which is to find the time of a skier? What would a code example be?

Since you know that the string array contain 5 names and the double array contains times corresponding to each of the names, you can just a for loop.

string name;
cin >> name;
for(int i = 0; i < 5; i++){
if(name == names[i]){
// fill this in yourself
}
}
