STRINGS AND FILE I/O

[SSHADOR]

Good Morning Motivators,

                                        I was trying to write a VI  which involves representing numbers in coded format, but I have no idea. Please help me if you can.

This is the question:

Suppose we want to represent numbers in coded format. Consider the following code:

            1 = lv, 2 = ma, 3 = po, 4 = ni, 5 = be, 6 = ut, 7 = ke, 8 = su, 9 = lu, and 0 = ha

            For example, the number 987 is written in coded form as lusuke. Create a VI that takes a string as an input and outputs the equivalent number on a numeric indicator. Display the number -1 if the input code does not translate.

You will need Search/Split Sting to get 2 characters at a time.  From there, use a lookup table to convert your two characters into a number (hint: use Search 1D Array which will give you the index of the match or -1 if there was no match).

Give it a try.  We will not do your homework for you.  If you have specific questions, ask away.

Hello everyone!

Here is my solution. I need to work more in my discipline of programming. 

If It works, It ain't stupid!

Regards!

General comment:

If you know how many times a loop will iterate, use a FOR loop.  In this case, you can use an autoindexing input tunnel to tell the loop how many times to iterate.  That would save you quite a bit of code in there (for FOR loop would just contain the Search 1D Array).

Define an enum that has your encodings, then use it to scan from string.

There was a discussion a while back where I remember where this can lead to false matches.  I can't remember why.

If there is not a match, you will still get a 0, so this will not meet the requirement of a -1 when there is an invalid code.

Who'd have known I'd be using this very code today?  😉

Hi Jimbe,

              I was looking at your snapshot and I had a quick question for you. How did you create the two tables ( One in pink and the other in blue)? Are they linked or something. I have trying to figure but no luck.

Thanks.
