Question

My professor just gave this to us today and I plan on working on this right when I get home, but if anybody can help me out beforehand by writing a "skeleton" program for me to work on modify myself, that would be great. Thanks in advance!

Write a program that will prompt the user to enter an integer between 0 and 999, and then print out the English phrase that represents this number. A sample dialog might be:
Enter an integer between 0 and 999: 375
This number in English is three hundred seventy five

The bulk of this program should be a function
    void numToEnglish(unsigned int num, char english[]);
The function fills the array english with the string that represents the number num.

Hints. You might find the following arrays of string literals useful:

char* first20[] = {“zero”, “one”, “two”, “three”, “four”, “five”,
“six”, “seven”, “eight”, “nine”, “ten”, “eleven”, “twelve”, “thirteen”, “fourteen”, “fifteen”, “sixteen”, “seventeen”, “eighteen”,
“nineteen”};
char* tens[] = {“twenty”, “thirty”, “forty”, “fifty”, “sixty”,
                “seventy”, “eighty”, “ninety”};

please rate - thanks

to get you started

    printf("Enter a two-digit number:: ");
    scanf("%d",&n);
    }
printf("You entered the number ");
units=n%10;
tens=n/10;
switch(tens)
   {case 1: switch(units)
