Decrypted Message, but not really.

[KAUFMANN]

Well, I have this message to decrypte the following way: each letter should be moved two rows ahead, so if we have ABC, the output should be CDE.

I've made the code, seems fine to me but doesn't work and I think there's a bug in my reasoning. Could you take a look?

#include <stdio.h>
#include <string.h>
int main(void){

	char msg[]="g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj";

	int i,k,len;
	len=strlen(msg);
	for(i=0;i<len;i++){
		printf("%c",msg[i+2]);}
	printf("\n");
	return 0;
}

If it is encrypted, shouldn't you be subtracting 2 to decrypt it? Also, it should be:

printf("%c", msg[ i ] -2 );

Becuase you want to subtract from the letter, not from the spot in the array (or add I guess).

OMG You're a freakin' genius! It totally worked Thank you so much. And to think that it was only a matter of puttin' there [i]+2 instead of [i+2]
I didn't know it made that much of a difference!

Thank you

x = array[ from_here + 2 ]; /* put the value of array spot 'from_here + 2' into x */
x = array[ from_here ] + 2; /* get the value of array spot 'from_here', then add 2 to that, and put it into x */

That's the difference between the two.
