What is the difference between an int and a long in C++?

...which has to fit within INT_MIN and INT_MAX. The C89 standard states that UINT_MAX should be at least 2^16-1, USHRT_MAX 2^16-1 and ULONG_MAX 2^32-1 . That makes a bit-count of at least 16 for short and int, and 32 for long. For char it states explicitly that it should have at least 8 bits (CHAR_BIT...

Average of 3 long integers

... I would suggest that a good way of dividing a 32-bit unsigned value by 3 is to multiply by 0x55555555L, add 0x55555555, and shift right by 32. Your divideby3 method, by comparison, looks as though it would require many discrete steps. – supercat ...
