Unless the first character was null, in which case it would be ignored by the condition... Also, you don't need to dereference a pointer in order to increase it

  haha, I was genuinely asking if it made sense, I don't usually do C. Maybe it helped illustrate that the code is too clever for me, at least. e: I submit my revised code: do { *dst = *src; src++; dst++; } while(*(dst - 1));

    Looking at src[-1] would work but feels like poor form. My advice is stop trying to make do ... while work here, it isn't looking good. I feel like more idiomatic iterating through a string tends to loop on src not being a terminator. while (*src) { *dst = *src; ++src; ++dst; } *dst = '\0'; I feel like this is idiomatic C but needlessly verbose. Most people would combine the increment with the assignment. And most people would recognize putting it in the while condition as a common strcpy.
