labview logic

Can please give me Idees for solving this logic ?

int32 y;
if(x=0)
y=0;
else(x>0 && x<=29)
y=1;
if else(x>=30 && x<=49)
y=2;
else y=3;

Wire x into a case structure.  You can make the case structure use number ranges.  In your case, you want a case that is "0", "1..29", "30..49', and DEFAULT (omit the quotes).

Now here is a good reason to read the Rube Goldberg thread.

There is more than one way to skin a cat.

The top is moderators solution.  Mine, on the bottom, does not need to edit code to add more cases.  Just build bigger arrays! (Of course thse constants become controls in real life- they are constants for demo only)

Do you really want an answer of "3" for negative inputs?

If we stick to positive inputs, the following gives equivalent results and is slightly more maintainable, especially of the number of cases is large.

Modify as needed...

You had 90% of the solution in your logic. Why not use a formula node?

I've also attached the VI (LabVIEW 2012)
