2.1 Task 1 [2 marks] In the staff.c file, in the "open_file()" function, write code to open/create an output file. You should name the file with your matric number (e.g. 1839303839.txt). If your matric number contains a dash, please remove it (e.g. matric no: 1834934344-1 File name: 18349343441.txt. DO NOT CLOSE the file. Then, in the first line, insert your matric number. The content of the created file should look like Figure 3. 1839303839.txt - Notepad File Edit Format View Help 1839303839 Figure 3. File content.
