Code:
char *strcpy(char*dest, char*orig)
{
char *tmp = dest;
while (*dest++ = *orig++)
;
return tmp;
}My question is, why is it "return tmp" and not "return *tmp"?

The return type of that function is a pointer-to-character (char*). dest, orig, and tmp are all pointers to specific memory locations that contain characters (actually, sequences of characters that make up strings, but they could also be single characters and the function would look the same). tmp is already a char*, a pointer to the memory address of the first byte of the copied string. That's the value you want to return. If you returned *tmp, you'd be dereferencing the pointer and instead returning the value of the first character of the copied string.
