how to compare string?

[michael12]

I have @a
foreach $a (@a) {print $a;}
the result is: a11,a12,a13....

also I have @b
foreach $b (@b) {print $b};
the result is: b11,b12,b13....

how can I set the condition to compare $a, $b, for example if a11=b11 then print "matched".

Is this what you want?

for ($i=0; $i<=$#a; $i++) {
    if ($a[$i] eq $b[$i]) {
        print &quot;$i matched \n&quot;;
    }
}

but how can use "foreach" at the same time?
do you mean:
foreach $a (@a) {
foreach $b (@b) {
for ($i=0; $i<=$#a; $i++) {
if ($a[$i] eq $b[$i]) {
print &quot;$i matched \n&quot;;
}
}

}

}

why do you want to insist on using foreach? Raider's for loop solution seems to do exactly what you want.

Hi

Try this out using &quot;foreach&quot;

foreach $a (@a) {
foreach $b (@b) {
if ($b eq $a) {
print &quot;$b Matched $a\n&quot;;
}
}
}
