Which of the following operations can be performed on the file "NOTES.TXT" using the below code?FILE *fp;fp = fopen("NOTES.TXT", "r+");

The code provided opens the file "NOTES.TXT" in "r+" mode. This mode stands for "read and write".

Here are the operations that can be performed on the file:

1. Reading: You can read the contents of the file using functions like fgets(), fscanf(), etc.

2. Writing: You can write to the file using functions like fputs(), fprintf(), etc. However, writing will not append to the file but will instead start overwriting the file from the beginning.

3. Updating: Since the file is opened in "r+" mode, you can both read and write to the file, effectively updating its contents.

4. Moving the file pointer: You can use functions like fseek(), rewind(), etc. to move the file pointer to different positions within the file.

5. Closing the file: After all operations are done, you can close the file using fclose() function.

Remember, the file must exist in your directory before you can open it with "r+" mode. If it does not exist, the fopen() function will return NULL.
