Command-line argument parsing

Different Command-line argument parsing methods are used by different programming languages to parse command-line arguments.

Programming languages

C

Main article: C_syntax § Command-line_arguments

C uses argv to process command-line arguments.^[1]

Java

An example of Java argument parsing would be:

public class Echo {
    public static void main (String[] args) {
        for (String s: args) {
            System.out.println(s);
        }
    }
}

PHP

PHP uses argc as a count of arguments and argv as an array containing the values of the arguments.^[2]
