The result is generated by calculating the difference between the addresses of the two pointers and calculating how many bits of data it is according to the pointer data type. That means we dont necessarily need the argument counter parameter argc to iterate through the command line arguments, we could also just loop through argv until we find the NULL pointer. Fixed now, thanks. Im not overly thrilled with C++ but I also havent kept up with it. and () have higher precedence than *. Beginner kit improvement advice - which lens should I consider? Thats pretty much all there is to know about the basics of pointer arithmetic. Only 1 * this code, or similar ;RESET POINTER HERE MOVLW B'11111111' MOVWF COUNT1 NEXTBYTE MOVF ""THIS WOULD BE THE POINTER"", W MOVWF OUT_BYTE CALL OUTPUT ;INCREMENT POINTER HERE DECFSZ COUNT1 GOTO NEXTBYTE If I do them all individually it will obviously take up quite a lot of code lines. We know that increment operation is equivalent to addition by one. Thanks in Advace Write your statements: int *p, *q, *r, *another_pointer, *andAnotherOne; I have no problem with this, and this is what I do. See http://c-faq.com/null/varieties.html. You really don't want to do thator, perhaps, why on earth do you think you want to do that (because you really don't want to do that!)? char buf[][] decays to char *buf[] is plain wrong, it decays to char(*)buf[], which is an array pointer to incomplete type (and therefore cant be used). Improve INSERT-per-second performance of SQLite. For performance, this often matches the width of the ref type, yet systems can allow less. Then, I can consult the precedence chart when writing the macro, and not having memorized it then has O(1) cost. Those are: 1. :). arrays) produced worse binary code, and using stupid pointer tricks compiled to the fastest implementations that you would have written were you programming in asm in the first place. The operators AND, OR, XOR, NOT, Shift Left, Shift Right are provided. This follows the same principle as the null-termination of strings, indicating the end of the array. Even if you write : 12 bytes. And as they taught me in school, O(1) ~ 0.
