void main(){
    int num,unit_digit,ten_digit,hundred_digit;
    char numbers[10][10] = {"Zero","One","Two","Three","Four",
        "Five","Six","Seven","Eight","Nine"};
    char tens[10][10] = {"","Ten","Twenty","Thirty","Forty",

    scanf("%d",&num);
    if(num<0 || num>999){
        printf("\nThe number is not between 0 and 999.");
        getch();
        exit(0);
    }
    unit_digit = num%10;
    num=num/10;
    ten_digit = num%10;
    num=num/10;
    hundred_digit = num;
    printf("\n");
    if(hundred_digit > 0){
        printf("%s Hundred ",numbers[hundred_digit]);
    }
    if(ten_digit == 1){
        printf("%s ",teens[ten_digit]);
    }
    else if(ten_digit > 1){
        printf("%s ",tens[ten_digit]);
    }
    if(unit_digit == 0){
        if(hundred_digit == 0 && ten_digit == 0){
            printf("%s",numbers[unit_digit]);
        }
    }
    else{
        printf("%s",numbers[unit_digit]);
    }
    getch();
}
