perl function printf

The printf function in Perl is used to format and print text and variables to the output. It is similar to the print function, but allows for more control over the formatting of the output. The basic syntax of the printf function is:

printf FORMAT, LIST

where FORMAT is a string that specifies the formatting of the output, and LIST is a list of values that will be printed according to the format.

Here's an example:

my $name = "Alice";
my $age = 30;
my $salary = 50000;

printf("Name: %s, Age: %d, Salary: \$%.2f\n", $name, $age, $salary);

Output:

Name: Alice, Age: 30, Salary: 000.00

In this example, the printf function is used to print the name, age, and salary of a person. The FORMAT string contains placeholders for the variables: %s for a string, %d for a decimal number, and %.2f for a floating-point number with two decimal places. The values of the variables are passed in the LIST argument, in the order that they appear in the format string.
