Take a look at these standard functions (in header <stdio.h>) :

1) fopen : opens a file
        http://www.cplusplus.com/reference/clibrary/cstdio/fopen.html

2) fclose : closes a file
        http://www.cplusplus.com/reference/clibrary/cstdio/fclose.html

3) fgets : read a line from a file
        http://www.cplusplus.com/reference/clibrary/cstdio/fgets.html

4) printf : write output to the standard output (screen)
        http://www.cplusplus.com/reference/clibrary/cstdio/printf.html

Also, make sure to look at the examples at the bottom of each of those pages ... they show you how to use the functions.


>> I hope you can return string value from main function.

Not with a return statement - main has to return int. You can send it to standard output using printf (see earlier), or you can write it to a file.
