The relationship of an array, pointers and command line arguments in C++ programming
Compiler: Visual C++ Express Edition 2005
Compiled on Platform: Windows 2003 Server Standard Edition
Header file: Standard
Additional project setting: Set project to be compiled as C++
Project -> your_project_name Properties -> Configuration Properties -> C/C++ -> Advanced -> Compiled As: Compiled as C++ Code (/TP)
Other info: This program must be run at command prompt
To do: Printing the command line arguments read from the standard input demonstrating the array, pointers and command line arguments in C++ programming
To show: The relationship of an array, pointers and the command line arguments in C/C++ programming
/* program to print arguments from command line, run this program at the command prompt */

or int wmain(int argc, WCHAR *argv[ ]) - Multibyte/Unicode
or int _tmain(int argc, TCHAR *argv[ ]) - Both: ANSI and Multibyte/Unicode

cout<<"argc = "<<argc<<endl;
for (i=0; i<argc; ++i)
cout<<"argv["<<i<<"]: "<<argv[i]<<endl;
