In the above solution
else {
str= Number2[number % 5];
number /= 5;
}

should be replaced by

else {
str= Number2[number % 10];
number /= 10;
if (number == 0) return str;
return Number2[number] + str;
}

The program does not handle case for 20, 30, 40 etc..

that is great but the problem here is user's input is required, and it has to convert from 0 to 20,000. but our teacher say if we can do it up to 100,000 he will give whoever does that a high grade. i don't know why with the program that i did it has error, if i type 1015 it will show one thousand tenfive fifteen. ANd out teacher says we have to use SWITCH
