All the indexes of array starts with 0.How to change the start index of array to "101";

Subtract 101 from the index. 

use constant BASE => 101;
$a[$i - BASE] = 'a';

This will still work: 

print("The array has ", 0+@a, " elements\n");
for (@a) {
    ...
}

without preventing you from doing 
for my $i (101..200) {
    ... $a[$i - BASE] ...
}

[download]

There's also $[, but

I'd avoid it.

Update: Compensated for a warning. There needs to be space between - and BASE.
