Anchors

Allow to fix the pattern into the specific part.

Example: \b is limiting the pattern into the word boundary.

#!/usr/bin/perl -w

print("Please Enter a sentence: \n");

while($_=)
{
if(/sky\b/)
{
print("Sky is at the end");
}

if(/\bsky/)
{
print("sky must at the beginning\n");
}

if(/sky\B/)
{
print("sky is not in boundries \n");
}

}


/B can use to find the sentences with that word is not at the end
