Answer 3

This code can't run here as we don't get to have files so I assume you ran it elsewhere. Your biggest mistake is name. You don't allocate any storage for it, just a uninitialized pointer. When you read into it, you might be overwriting your code or other data variables. If you are lucky, you ran it on a system with memory protection so it crashes with an access violation error. Unlucky and your code could randomly erase your hard drive.

Answer 7

Change line 9 to:
char a,name[100];

to allow 100 character names. It should run on your PC or phone with compile/IDE.

Answer 8

You have non-standard C++ includes so may only work with obsolete Turbo C++ on PC.

Answer 9

Btw fseek(f1,-1,1); for ?

Answer 10

That attempts to position to the character before the beginning of the file. Not sure what the result would be.
fseek(f1,-1,3);
Would be to read the last character as 3 picks the end of file.
