Question
Which of the following operations can be performed on the file "NOTES.TXT" using the below code?FILE *fp;fp = fopen("NOTES.TXT", "r+");
Solution
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:
-
Reading: You can read the contents of the file. This is done using functions like
fscanf(),fgets(),fgetc(), etc. -
Writing: You can write to the file. However, writing will not append to the end of the file, but will instead start overwriting the file from the beginning. This is done using functions like
fprintf(),fputs(),fputc(), etc. -
Updating: Since the file is opened in "r+" mode, it allows both reading and writing operations. Therefore, you can update the contents of the file.
-
Moving the file pointer: You can move the file pointer to different positions in the file using the
fseek()function. This allows you to read from or write to specific locations in the file.
Please note that if the file "NOTES.TXT" does not exist, the fopen() function will return NULL and none of these operations can be performed.
