write a c program to read,write and append file using switch case?

[WannaBLostinLuv]

actually im tryin to do basics of file handling.....

 

[VinceF]

so what's your question?

If you're simply lost, start by reading man pages for:

open()
close()
read()
write()
lseek()

and

fopen()
fclose()
fread()
fwrite()
fseek()

That's all you need for basic file handling.

Good luck
