ram to run automatically in c

Not sure whether this is what you're asking but, when you pass a file path as a command line argument, it's not necessary to double the backslashes and it would in fact be a mistake to do so. 

You only need to do this when you're including the path in a string literal because otherwise the C compiler would conclude that the backslash was beginning an escape sequence such as \n, \t etc.

Notice though that if a command line argument includes embedded spaces, then you should enclose the whole argument in double quotes.
