✐ Examples

1 Convert Strings to Integers

In this example,

We have an array of strings named @strArray containing string representations of integers.
We use the map function to transform each element of @strArray to an integer using the `<=>` operator.
The resulting array @intArray contains the converted integers.
We print the contents of @intArray to demonstrate the conversion.

Perl Program

@strArray = ("10", "20", "30");
@intArray = map { $_ <=> 0 } @strArray;
print "Converted array of integers: @intArray\n";

Output

Converted array of integers: 10 20 30
