Could someone convert this code into one where you can input the file directory from the console?

This code works but te directory can only be changed from the code not the console.

pretty compact code... However, change the main header to:
int main( int argc, char **argv )
argc will be the number of paramters from the command line including the application name, i.e. it is at least 1.
argv is an array of c-strings holding the arguments, e.g. argv[0] is the application name.
calling the application like:
myapp 123 "hello world"
will result in argc being 3
argv[0] is "myapp\0"
argv[1] is "123\0"
argv[2] is "hello world\0"
where '\0' is the c-string terminator.

This doesn't work either.
