262 WITHOUT the analysis function? You gotta do it in under 51 tokens then.
- Code: Select all
#include <stdio.h>
char*_="XxTIHRCXCxTIHRXRCxTIHXHRCxTIXIHRCxTXTIHRCxXxTIHRCX";
int main(int l){for(l+=7;l!=putchar(010);++l);if(*(++_))main
(*_!=88?(putchar(*_^073)|putchar(33))&1:0xffff2a8b);}

What type of libraries can we include?
I'm using a function that's in the string.h-library (I guess it's <cstring> for modern compilers?). But the function still works even without including <cstring>. Must I still include it?
Btw: 195

any standard library header
My analysis section is pretty big.
Also, how do you make a pointer to an unsigned char and assign it to a literal string?
unsigned char* var = "this is my string with extended ascii codes in it";
gives me an error.
DECLARATIONS 65
ANALYSIS 264
MAIN(INPUT/OUTPUT/LOGIC FLOW) 118

I was afraid you'd say that, I was hoping there could be a suffix(or prefix) I could put on the string to do it.

Perhaps there is something similar you could use.
- Code: Select all
short my16bitvar = L"\0200\0201"[index]; // 8 tokens

there is a sticky thread where you can download the results for that contest, however, all of the ones on the page you posted are c++ except the one written in corsix script

Please, just give me a link where they show how
"\x0 asd as whatever"[variable]
works.
I'm talking about the string and what the string transforms to (an array?).
Btw: are we allowed to write include "iostream"?

The expression `A[B]' just means `*(A+B)'. A string constant has type `const char *', and its value is the address of the first character of the string, so
"foo"[var] == *("foo"+var),
which is the character `var' places after the beginning of the string constant.
An even more obscure way of doing the same thing is reversing the operands, like this:
variable["some string here"]
"foo"[var] == *("foo"+var),
which is the character `var' places after the beginning of the string constant.

I was going to dis-allow it, but then there were some complaints and I said if no one objected I would allow it and no one has objected so I guess it's allowed
[edit]
corsix, Beerhunter .. I'm coming for you guys...
393... just got rid of my last function, everything is in main and no duplication.
