Answer 1

Danila Khaminets The command line gets passed into main through its input parameters.

int main(int argc, char *argv[]);

argc - the count of command line strings in argv
*argv[] - the command line string values (C strings, NULL-terminated)

argv[0] will be the program name itself
argv[1], argv[2], ... will be the added elements after the program name.

In your case, argc will be 2; argv[0] will point to "some_app.exe" and argv[1] will point to "file.txt".
