i remember a post how to realize swap(int x,int y) the fastest way, and without a buffer-value means: no swap(int& x,int& y) { int buffer=x; x=y; y=buffer; } ,thats not allowed after learning alittle bout asm and so, i wrote now 3 nice makros everyone could use: #define swap32(a,b) __asm{mov eax,(a)}__asm{xchg eax,(b)}__asm{mov (a),eax} #define swap16(a,b) __asm{mov ax,(a)}__asm{xchg ax,(b)}__asm{mov (a),ax} #define swap8(a,b) __asm{mov al,(a)}__asm{xchg al,(b)}__asm{mov (a),al} with them you can swap two chars,short/long ints,floats with just 3 asm calls, u just have to use the right version: char x=23,y=34; swap8(x,y); or float x=24.34f,y=3254.21f; swap32(x,y); hope this helps alittle we wanna play, not watch the pictures

nice one mate you could also use this in c
a ^= b ^= a ^= b;

look at the asm code of your ^=^=^=, bout 6 asm statements, i think.. mine has just 3

but yours is a nice fast way in c/c++

btw, my statement also works for floats, how bout yours?

Those two statement will probably run as equivalent code since xchg will be broken down when compiled, into move than other statements

it doesnt change on my pc, i looked at the asm-source
