C Language Learning 011: main function with parameters

Directly on the code

1#include <stdio.h>2 3 intMainintargcChar*argv[]) {4printf"%i \ n", argc);5     inti;6      for(i =0; i < argc; i++){7printf"%s\n", Argv[i]);8     }9     Ten     return 0; One}

In the main method above, the first parameter argc represents the number of elements in the array, the second parameter *ARGV represents the parameter array, that is, argc represents the length of the *argv; Interestingly, the first element of *ARGV is the name of the program.

The parameters need to be separated by a space, otherwise the parameters will be linked together

At the same time, the program can not contain both the main and the parameter of the main function, compile will prompt to redefine the main function, such as
