print name of number

First, separate your given number in to tens and ones. (e.g. if your number is 23, int tens = 2; and int ones = 3;.) You can use the modulus operator to accomplish this programmatically.

Next, use a switch statement to print the name of the tens digit.

switch( tens )
{
case 2:
    printf("twenty");
case 3:
    printf("thirty");
// ...
}

Finally, use a second switch statement to print the name of the ones digit:

switch( ones )
{
case 1:
    printf("one")
case 2:
    printf("two");
// ...
}

That's it!
