I understand that String[] args is an array of strings passed into main as parameters.
java Print "Hello, World!"
class Print { public static void main(String[] args) { System.out.println(args[0]); } }
However, when you don't include it as a parameter...

There's no significant.
Any of
static void Main() static void Main(string[] args) static int Main() static int Main(string[] args)
Ultimately it doesn't make a lot of difference, to be honest.

It shall have a return type of type int, but otherwise its type is implementation-defined.
When starting a program using exec you can set that to an arbitrary value:

Say you have 2 functions:
void func(int x,int y,...) { //do stuff } void func2(int x,...) { func(x,123,...); }
How can you make this work, e.g pass the arg-list to the other function?
EDIT: this is a duplicate , can someone merge them or whatever?

You need a separate version that works with explicit argument lists:
void vfunc(int x, va_list args) { /* do stuff */ } void func2(int x, ...) { va_list arg; va_start(arg, x); vfunc(x, arg); va_end(arg)....

We need to pass a format _TCHAR * string, and a number of char * strings into a function with variable-length args:
inline void FooBar(const _TCHAR *szFmt, const char *cArgs, ...) { //... }
So it can be called like so:
char *foo = "foo"; char *bar = "...

I have a string with quotes around the path as follows:
"C:\Program Files (x86)\Windows Media Player\wmplayer.exe" arg1 arg2
If I use Text.Split(new Char[] { ' ' }, 2); then I get the first space.
How to get the path and args ?

I may have a syntax(input); for (int i = 0; i < mc.Count; i++) { Console.WriteLine(mc[i].Value); }.
