Re: comparing elements of two arrays

Your code works for me:

@array1[2] = @array2[2] = 'hi';
if ($array2[2]  eq $array1[2] )
    {
        print $array2[2];  print "\n";
    }
# prints this: hi

I suspect I'm missing something, though.

Could you post your arrays, too? I think a little more detail is needed.

Remember that 'eq' is for strings, and '==' is for numbers.

mrbbking is right, we need more info from you. After seeing the solution for array from file and compare, i wonder if you need to chomp at least one of your arrays first. jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR F--F--F--F--F--F--F--F-- (the triplet paradiddle)	[reply]

My arrays are strings. Each elements is one line from a file. This is how I read the data and insert it into 2 arrays: `$infile1 = "sept13.csv"; $infile2 = "sept14.csv"; open (infile1); @array1=<infile1>; close(infile1); open (infile2); @array2=<infile2>; close(infile2);` [download] `The format of file(.csv) is as follows.

Slurping the whole file in like that results in a one-element array. So there is nothing at subscript 2 to compare. You'll need to split the lines of each file into their component parts before you can compare (what appears to be) usernames. ...does that make sense?	[reply]
