Request - Can someone post a example of case selection?

FeniX · **Posted:** Fri Jun 20, 2003 8:50 am

If I am correct case selection has to do with if statements right?
well thank you to whoever posts an example.

ya ur rite, its a simple way to do if statements

krishon · **Posted:** Fri Jun 20, 2003 9:53 am

yah..for example

code:

var char : string

put "Enter a letter grade."
get char

case char of:

label "A"
put "Good job"
label "B"
put "Nice work, your almost there."
label "C"
put "That's ok, try harder."
label "D"
put "You have to get your act into gear quick."
label "F"
put "Your a failure."
label ""
put "You entered an invalid grade, try again."
end case

its somethin like this, i forgot the format cuz i haven't used it in a while

that looks like Ti 83+ plus programming

krishon · **Posted:** Fri Jun 20, 2003 9:57 am

lol, TI 83+ programming is much worse...god it takes so long just to do a stupid quadratic formula program.

Andy · **Posted:** Wed Jun 25, 2003 11:43 am

no it doesn't... making a quadratic program is easy, making a factoring program takes a long time

case still sucks cuz it's getch. i'd prefer input.keydown myself

case is sorta easier 2 work with

????????????
case = getch?
????????????

I always thought case was an alternate if thingie.

it is an alternate, but _restricted_, if statement syntax.
just a cosmetic feature of the language.

AsianSensation · **Posted:** Sat Jun 28, 2003 10:42 am

so why is case used if it is more restricted, and therefore, offers less options then if? Does it compile quicker or something? Or is it just more user friendly? (but if/then is very user friendly....I don't see how you can get more simpler by using case....)

why do they have more than one type of operating system? its all about preference

naoki · **Posted:** Sat Jun 28, 2003 1:36 pm

get char

case char of:

label "A"
put "Good job"

that's basically like getch in a sense (but more towards if statements).

Catalyst · **Posted:** Sat Jun 28, 2003 2:01 pm

it isnt like getch, its a basic language construct altho everything it does can be done using ifs and elsifs (or just ifs and elses for that matter)

PaddyLong · **Posted:** Sat Jun 28, 2003 2:25 pm

they are also very helpful in languages like Java where you don't have any elseif statement... just if and else...

so like you could have (not using java syntax, but the idea...)

code:

if this = a then
do this
else
if this = b then
do this
else
if this = c then
do this
end if
end if
end if

or you could just have (not using java syntax, but the idea...)

code:

case this of:
label a:
do this
label b:
do this
label c:
do this
end case

so probably it's in Turing to teach you (because as we all know, turing is just for learning to program Rolling Eyes

) about them, so when you go to learn something like Java, you aren't like wtf is this??

paddylong, is there no elsif in java?
