Hi all,

I am having problem with array while setting the flag,

actaully when i get the array size should be all 44 other wise it should  
come to flag 0, now my array counts are 42 42 44, so it shows the flag =  
0, but for me it showing flag =1 , i think i have some loop problem,  
please let me know why?

@split\_record.each do |v|  
@split\_data=v.split("\*")  
@get\_size=@split\_data.size // after split my array is  
42 42 44  
if @get\_size == 44  
@flag=1  
else  
@flag=0  
end  
end  
return @flag

In this i am checking 3 records, i should get flag=1 if all are 44,  
but at present not matching, so it should shows floag=0, but for its  
showing flag =1, please let me know the problem, thanks in advance

And this question is suited for ruby-lang

1. just from the code here it seems there is no need for u to use global  
variables (why not use local variables? better for mem usage). →   
instead of using  
@get\_size  
why not just use  
get\_size

2. the reason, simply, that the @flag=1 has to do with the fact that in  
the last iteration (=loop) the flag is set to one because the last var  
in the array is  
44, so if u check the value of the flag per loop you’ll get:

(begin loop)  
loop 1: @flag=0  
loop 2: @flag=0  
loop 3: @flag=1  
(end loop)

at the end of the loop, the variable @flag equals 1.
