Number to Word Conversion

Question

C programming.

Write a C program that will accept an amount (in number with decimal) from the user and converts it to word equivalent. The program should follow the following rules:

1.use user-defined functions, string, array, loops, and other useful codes

2.input limit is a maximum of 10000.00

3. after each display of output, ask to user if he/she wants to convert another amount (if Yes, redo, else exit)
