How to Convert a Set of Strings to a Set of Integers in Perl - Step by Step Examples

How to Convert a Set of Strings to a Set of Integers in Perl ?

Answer

In Perl, you can convert a set of strings to a set of integers by iterating over each element and using the Perl built-in function `push` to add the converted integers to a new set.

✐ Examples

1 Convert a Set of Strings to a Set of Integers using foreach Loop

In this example,

We have a set named @string_set1 containing the elements '1', '2', '3', '4', '5'.
We iterate over each element of @string_set1 using a foreach loop.
Within the loop, we use the `push` function to add each converted integer element to @int_set1.
We print the resulting @int_set1.

Perl Program

@string_set1 = ('1', '2', '3', '4', '5');
@int_set1 = ();
foreach $str (@string_set1) {
    push @int_set1, int($str);
}
print join(', ', @int_set1);

Output

1, 2, 3, 4, 5

2 Convert a Set of Strings to a Set of Integers using map Function

In this example,

We have a set named @string_set2 containing the elements '10', '20', '30', '40', '50'.
We use the `map` function to apply the conversion to each element of @string_set2.
We print the resulting @int_set2.

Perl Program

@string_set2 = ('10', '20', '30', '40', '50');
@int_set2 = map { int($_) } @string_set2;
print join(', ', @int_set2);

Output

10, 20, 30, 40, 50
