- 'myfile.c' does not exist on the disk
- 'myfile.c' exists on the disk
Ans:
1. If "myfile.c" exist in the disk, so simple FILE pointer fp points to the file.
2. If "myfile.c" do not exist in the disk, so as the opening mode is "r" read-only, so no new file is created and fopen() returns a NULL assigned to fp.
