How do you format an unsigned long long int using printf?
...y want to try using the inttypes.h library that gives you types such as
int32_t, int64_t, uint64_t etc.
You can then use its macros such as:
uint64_t x;
uint32_t y;
printf("x: %"PRId64", y: %"PRId32"\n", x, y);
This is "guaranteed" to not give you the same trouble as long, unsigned long long etc...
What is the difference between range and xrange functions in Python 2.X?
...plementation of Python currently restricts its args to C longs:
xrange(2**32-1, 2**32+1) # When long is 32 bits, OverflowError: Python int too large to convert to C long
range(2**32-1, 2**32+1) # OK --> [4294967295L, 4294967296L]
Note that in Python 3.0 there is only range and it behaves li...

Which is faster : if (bool) or if(int)?
...s an 8-bit value, and your system ABI requires it to "promote" small (< 32-bit) integer arguments to 32-bit when pushing them onto the call stack. So to compare a bool, the compiler generates code to isolate the least significant byte of the 32-bit argument that g receives, and compares it with c...
