Neither one really has a direct "equivalent" in assembly. Prefix is going to look something like: inc eax # increment the value mov eax,ecx # copy the ret

Neither one really has a direct "equivalent" in assembly. Prefix is going to look something like: inc eax # increment the value mov eax,ecx # copy the return value to its destination Postfix is going to look something like: mov eax,ebx # copy original value inc eax # increment value mov ebx,ecx # copy original value to final destination The actual code you'd get would vary a lot between compilers, architectures, and even just different contexts within the same compiler-architecture combination.
