A quoted string can be embedded in an argument. Within a quoted string, a pair of double quote marks is interpreted as a single escaped double quote mark. If the command line ends before a closing double quote mark is found, then all the characters read so far are output as the last argument. The double quote mark is interpreted as an escape sequence by the remaining backslash, causing a literal double quote mark " to be placed in argv.
The following table shows example input and expected output, demonstrating the rules in the preceding list. The Microsoft compiler optionally allows you to use wildcard characters, the question mark? Command-line arguments are handled by an internal routine in the runtime startup code, which by default doesn't expand wildcards into separate strings in the argv string array. You can enable wildcard expansion by including the setargv. For more information on runtime startup linker options, see Link options.
If your program doesn't take command-line arguments, you can suppress the command-line processing routine to save a small amount of space. To suppress its use, include the noarg. Similarly, if you never access the environment table through the envp argument, you can suppress the internal environment-processing routine. To suppress its use, include the noenv.
Your program might make calls to the spawn or exec family of routines in the C runtime library. If it does, you shouldn't suppress the environment-processing routine, since it's used to pass an environment from the parent process to the child process.

However my problem is not yet resolved, so I did not choose the right answer yet. So if I edit the question, I guess others who have already answered won't get notified. I read online that I should simply comment here so that others can notice that I have edited my question.
So I wanted all of you to know that I have edited my question and I want answer for that. Thanks a lot for your help. Leaving a comment like "Edited my question" does not notify anyone but it helps those who re-visit to immediately notice your update.
With so many answers that's enough. If you ever happen to get only a single answer, your best bet is to comment the answer instead of your question - this really notifies the author of the answer.

With the later referencing char -arrays, C-"strings". An " array of strings " definitely is something different char[47][11] for example. Also the const in you example signatures for main is wrong, at least for C. In your edited question you have fixed your main problem. Now notice that your prompt looks like. Ruslan Ruslan You can refer the document : As you can see, main now has arguments. Rahul Tripathi Rahul Tripathi k 30 30 gold badges silver badges bronze badges.
