Step 1 to read the utmp file. Exercise 2: 1. fread and fwrite: Use fopen, fread, and fclose to implement the who command. 2. fseek: Use fseek to locate the last and fourth user information of the utmp file and start reading. 5. fsetpos and fgetpos. Use fsetpos to implement the functions in step 2. 3. sprintf atoi: Use sprint atoi to convert data types (integer to string, character to integer), display or use GDB debugging to observe data. 4. fprintf and fscanf: Use

three common functions: separating the path to find the file name. Find the drive letter (Windows system) and find out the file extension.
