If I have a Program.exe that takes input and print it.
If I want to run this program from the cmd I will go to its directory and write Program.exe (enter).
And what is going to happen a new line and waiting for the input.
But what if I want to give the input at the same line like that :

c:\Users\abc> Program.exe input
and that's it the program doesn't ask for input(as I gave it at the same line when I invoked the program) and print the output and terminate

I am working with c++.
