That's odd, I get "error: stray '\' in program"

How about posting a copy of a complete compilable program.

You don't, the program will not compile because of a stray '\'.

Interesting that you say that...

On my system, I get S, just like the OP.

Obama could cure cancer tomorrow, and the Republicans would be
complaining that he had ruined the pharmaceutical business.

(Heard on Stephanie Miller = but the sad thing is that there is an awful lot
of direct truth in it. We've constructed an economy in which eliminating
cancer would be a horrible disaster. There are many other such examples.)

That's the whole code:

----------------------
#include<stdio.h>

char input[]="SSSWILTECH1\1\11W\1WALLMP1";

main()
{
int i,c;


for( i=2; (c=input[i])!='\0'; i++){
switch(c){
case 'a' : putchar('i'); continue;
case '1' : break;
case 1 : while( (c=input[++i])!='\1' && c!='\0');
case 9 : putchar('S');
case 'E' : case 'L' : continue;
default : putchar(c); continue;
}
putchar(' ');
}
putchar('\n');
}
------------------------
Additionally i have question how: /*case 'E' : case 'L' : continue; */
works, and what is the difference between /* case 1 */ and /* case '1'
*/

Regards

OK, then I suggest you to study your compiler documentation for
the meaning of the diagnostic message "S". You apparently know
little about C, but believe me: the statement above requires a
diagnostic message and those have to be documented by the
implementation.

Ok, wrong question asked, why: printf("%d", '\11'); gives 9 ?? What
this \ means ?

In this case, it introduces an octal constant. Octal 11 is
decimal 9.
