The difference between return and exit()?

Hi,
I often see the functions like exit() and close(). Can they replace
return in the c program? Which header includes them?
What is the difference between exit(0), exit(1) and exit(...)?
Please give me some examples.

Thanks,

exit() causes the program to exit with the argument as return value.
The return statement only returns from a function to its caller.  In
main(), this amounts to exiting the program.  close() is for closing
files opened with open().

Use the command "man" to view the manual for these function.  Running
"man exit" will give information on the exit() function, etc.
