C - Maximum exit code
=====================

Public domain
********************************************************************************


    /* Because of atoi(), at least stdlib.h
     * should be included. But this program
     * compiles without any #include.
     * I don't know why.
     */
    main(int argc,char *argv[])
    {
            return atoi(argv[1]); 
    }

********************************************************************************
### Output

It seems 255 is the maximum exit code.


    $ ./a.out 12
    
    $ echo $?
    12
    
    $ ./a.out 255
    
    $ echo $?
    255
    
    $ ./a.out 256
    
    $ echo $?
    0
    
    $ ./a.out 257
    
    $ echo $?
    1
