C++

1. Parameters of the main function

   • argc is short for argument count: the number of arguments passed to main;

   • argv is short for argument vector: the sequence of (pointers to) arguments passed to main. The first argument argv[0] is always the program name and includes the program’s full path, so strictly speaking the number of arguments we need to supply to main is argc-1;

   #include <iostream>
   
   using namespace std;
   
   void main(int argc,char *argv[])
   {
       for(int i=0;i<argc;i++)
       {
           cout<<"argument["<<i<<"] is: "<<argv[i]<<endl;
       }
       system("pause");
   }
