1. (a) Extend code snippet 1 to check for read and write access permissions of a given file:

(b) Write a C program where open system call creates a new file (say, destination.txt) and then opens it. (Hint: use the bitwise OR flag)

Example code snippet (incomplete) with system call (written Snippet 1: check_file_permissions.c int main (int argc, char* argv[]) \{ char* filepath = argv[1]; int returnval; // Check file existence returnval = access (filepath, F_OK); if (returnval == ) printf (" \%s exists ", filepath); else \{ if (errno == ENOENT) printf ("\%s does not exist ", filepath); else if (errno == EACCES) printf ("\%s is not accessible ", filepath); return ; // Check read access // Check write access return
