/simple correct....@shobhit Can u little bit explain?

---

$argv$ contains all the parameters passed to it through command line and the filename, $argc$ contains the count of the parameters passed +1 for the filename

For eg. ./fname param1 param2

argc = 3(count of parameters +1 for filename)

argv = [ "./fname", "param1", "param2" ] 

At last we can say, $argv$ is the argument to the main function, and $argc$ takes count of it and $+1$ for storing the filename.

argv[0] will print ./simple

argv[1] will print hello

argv[2] will print world

and argc will print 3
