Determining complexity for recursive functions (Big O notation)
...ften Big O notation and complexity analysis uses base 2.
void recursiveFun4(int n, int m, int o)
{
if (n <= 0)
{
printf("%d, %d\n",m, o);
}
else
{
recursiveFun4(n-1, m+1, o);
recursiveFun4(n-1, m, o+1);
}
}
Here, it's O(2^n), or exponential, since...

How do I convert between big-endian and little-endian values in C++?
...2 bit numbers:
unsigned long _byteswap_ulong(unsigned long value);
For 64 bit numbers:
unsigned __int64 _byteswap_uint64(unsigned __int64 value);
8 bit numbers (chars) don't need to be converted.
Also these are only defined for unsigned values they work for signed integers as well.
For float...
Replacing a 32-bit loop counter with 64-bit introduces crazy performance deviations with _mm_popcnt_
...a very weird effect: Changing the loop variable from unsigned to uint64_t made the performance drop by 50% on my PC.
