For example, if I have a network spec like 172.20.10.0/24, "24" is the bitcount. What's the best way to convert that to a netmask like 0xffffff00 ?

In a sequence of length n, where n=2k+3, that is there are k unique numbers appeared twice, how to find the three unique numbers that appeared only once using bit manipulation?
for example, in sequence 1 1 2 6 3 6 5 7 7 the three unique numbers are 2 3 5.

I didn't know any better name for a title of the question.
For ex: on one of my previous questions one answered ((a)-(b))&0x80000000) 31 - this is kind of a too advanced for me and i can't really get what it means. I am not looking just for an answer of that, but i need someone to tell me some…

Hi.
I am trying to make a loop that loops through all different integers where exactly 10 of the last 40 bits are set high, the rest set low. The reason is that I have a map with 40 different values, and I want to sum all different ways ten of these values can be multiplied. (This is just out of…

I have a fragment of bytes in a byte[]. The total size of the array is 4 and I want to convert this into a positive long number. For example if the byte array is having four bytes 101, 110, 10, 1 then i want to get the long number represented by binary sequence
00000000 00000000 00000000 00000000…

Hi,
I am stuck with a problem. I am working on a hardware which only does support 32 bit operations.
sizeof(int64_t) is 4. Sizeof(int) is 4.
and I am porting an application which assumes size of int64_t to be 8 bytes. The problem is it has this macro
BIG_MULL(a,b) ( (int64_t)(a) *…
