The main function is a good example of how a C + + program can pass an array to a function.Sometimes we need to pass arguments to main, which defines the main functionint Main (intChar *argv[]); // argv represents an array whose elements are pointers to C-style strings // ARGC represents the number of strings in a function // argv The first element points to the name of the program or an empty string, the next element is to pass the

We often use a program in Linux to add parameters, and now it is much more powerful to understand the module Getopt::long in Perl about control parameters than to use @ARGV arrays directly. I think you know there are two different types of parameters in Linux. • Long Parameter –help• Short Parameters-HThat is--and--the distinction. – Represents the full parameter.-Represents a simplified parameter. These two methods are supported in this module of Perl.This is to introduce the two Getopt actual

special variables to achieve this purpose: one is the $ argv variable, which saves the parameters passed to the PHP script as separate array elements through the command line; the other is the $ argc variable, which is used to save the number of elements in the $ argv array. It is very easy to write a piece of code that reads $ argv and processes the parameters it contains in a PHP script to see how it wor
