Rush02

MVP

Create a program that takes a number as argument and converts it to its written letters value.

Turn-in directory: ex00/

Files to turn in: Makefile and all the necessary files

Allowed functions : write, malloc, free, open, read, close

---

• Executable name: rush-02
• Your source code will be compiled as follows :

make fclean
make

• Your program can take up to 2 arguments:
  • If there is only one argument, it is the value you need to convert
  • If there are two arguments, the first argument is the new reference dictionary and the second argument is the value you need to convert.
• If the argument isn’t a valid positive integer, your program must return "Error", followed by a newline.
• Your program must parse the dictionary given as resource to the project. The values inside it must be used to print the result. These values can be modified.
• Any memory allocated on the heap (with malloc(3)) must be freed correctly. This will be verified during evaluation.
• The dictionary will have the following rules:

[a number][0 to n spaces]:[0 to n spaces][any printable characters]\n

• You will trim the spaces before and after the value in the dictionary.
• The dictionary will always have at least the keys as in the reference dictionary.
  • Their value can be modified, more entries can be added, but the initial keys can’t be removed.
• You only need to use the initial entries (For instance, if we add 54: fifty-four, you still have to use 50: fifty and 4: four)
  • The entries of the dictionary can be stored in any order.
  • There can be empty lines in the dictionary.
  • If you have any errors from the dictionary parsing, your program must output Dict Error\n
  • If the dictionary doesn’t allow you to resolve the asked value, your programmust output Dict Error\n.
• Example:

$> ./rush-02 42 | cat -e
forty two$
$> ./rush-02 0 | cat -e
zero$
$> ./rush-02 10.4 | cat -e
error$
$> ./rush-02 100000 | cat -e
one hundred thousand$
$> grep "20" numbers.dict | cat -e
20 : hey everybody !$
$> ./rush-02 20 | cat -e
hey everybody !$

Bonus

• Use customized key-value data: 54: fifty-four instead of 50: fifty and 4: four
• Using -, ,, and to be closer to the correct written syntax
• Doing the same exercice in a different language. For this, you are allowed to provide another dictionary which will contain the necessary entries.
• Using read to read standard entry when there is no argument
• Any other bonus that you think bring something more to the project
