Les chiffres: how to spell numbers in French

Using the names of numbers is a useful at an early stage in learning another language.

requirement

Store the spelling of the numbers 0 to 5 in French. An array will be needed to store the list of six French words. Display each number digit along with the French spelling. The user can then read and try to memorise each number spelling. Allow the user to choose any number by typing in the digit and the program should display the spelling for that word. The user can try to predict the spelling and then ask the program to show the correct spelling.

output

the full list on number names in French, the number name for the number chosen by the user

process

no calculations required

algorithm

1. store the names of the numbers 0 to 5 in French

2. display the first stored number 0

3. display the second stored number 1

4. display the third stored number 2

5. display the fourth stored number 3

6. display the fifth stored number 4

7. display the sixth stored number 5

8. ask the user to enter a number to spell

9. display the number name for the number entered by the user

code features

store a list using an array

String[] numberNames = {"zéro", "un", "deux", "trois", "quatre", "cinq"};

Declare a String array called numberNames and initialise it to store the six text values in the order shown

Notice the [ ] brackets after the term String, this show that it is an array and not an ordinary single value string.

Notice the { } brackets surrounding the list of text values

Notice the " " for each value and the commas separating each value

Notice that there are six values, 0-5

Notice that the the digit 0 is in first position and 5 is in sixth position

display a value from an array

System.out.println( 0 + " - " + numberNames[0]);

numberNames[0] identifies the array and the position of the element to be used, 0 is the position of the first element

System.out.println( spellDigit + " - " + numberNames[spellDigit]);

numberNames[spellDigit] identifies the array and the position of the element to be used, spellDigit is a variable that should have been set to any value 0-5

PRIMM

predict

* what word will be displayed when the digit 1 is entered

* what value should be entered to display "cinq"

investigate

what happens if you enter the value 6

what happens when you enter the value -1

what happens when you enter the value 3.5 or 1.0

modify

The next set of French words for the numbers 6-10 are:

six, sept, huit, neuf, dix

Can you edit your code to include the new words at the end of the existing list. Then get the program to display all the numbers up to 10. Can you anticipate what position the word "dix" will be in?
