Case Structures, Strings and ~ (tilde)

[SercoSteveB]

What is the value in 'String Value Out' following execution of the VI?

The single hidden case of the Case Structure is shown below.

a) every equivalent each

b) every equivalent answer allows each available atom

c) each

d) <empty string>

This is another one that I might consider a little difficult for the CLAD.  Maybe you should submit this one as a CLD-R.

A.

But I am assuming that the "~" character comes really late in the ASCII list.  I didn't know off hand.

I spend way too much time when I have to deal with parcing strings.  Too many tricks/qwerks with the regular expressions and special characters.

ans is A

ANS:- A

A textual range syntax for the Case Structure,  might be useful?

[mini09]

may i know what is the function of ~ in the case structure?

I also go with A...

[crossrulz]

~ is just an ASCII character.

[GayatriT]

Ans is A

why it is used here what is the i don get it? "ea".. "~"

What do you not get?  The ".." just creates a range.  The case "ea".."~" will execute for a string that comes between "ea" and "~" using the ASCII values.

My question is what is the string value of ASCII character ~. How the ASCII and the string forms a range?

The ~ is ASCII character 0x7E (or 126 if you want decimal).  Look up an ASCII table and things will make a lot more sense.

PLS EXPLAIN THE SOLUTION OF THIS QUESTION

[crossrulz]

What part do you not understand?  Reading through the posts, I feel like we explained this decently well.

[santoshsss]

sir, from the beginning, because i am a bit raw in strings used in case structure. pls can u explain me this question step by step. thank you

[santoshsss]

and also i forgot to mention, i tried this code , but i am getting other output

[crossrulz]

You can do a direct comparison of strings with case structure.  So you can have a case "blah".  So when your string is "blah", it will run that case.

What was introduced here is a range of possible strings.  The ".." creates the range.  In this case "ea".."~" creates a range between "ea" and "~".  So alphabetically anything starting with an "ea" or later up to the "~" will run this case.  The comparison is based on the ASCII values of the characters, so make sure you have an ASCII table sitting around.

[santoshsss]

thank you crossrul, do we have to compare the ranges thru ascii values?

[crossrulz]

when dealing with strings, it always boils down the the ASCII value.
