Bits in a char
WebIf you want to access the last 4 bits you can use unsigned char v = (*single_char) & 0x0F; If you want to access the higher 4 bits you can just shift the mask up 4 ie. In the specific case of the TCP header, the lower 4 bits of this octet are reserved and must be zero. WebBit Fields. Bit Fields allow the packing of data in a structure. This is especially useful when memory or data storage is at a premium. Typical examples: Packing several objects into a machine word. e.g. 1 bit flags can be compacted. Reading external file formats -- non-standard file formats could be read in. E.g. 9 bit integers.

WebThe minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer … WebIt's hard to read. Spell it like n > 0 or n!=0 since conditional operators evaluate to ints in C. To address point two, I'd consider the following, which is simplified a bit for ease of understanding. void printBits (unsigned int num) { for (int bit=0;bit< (sizeof (unsigned int) * 8); bit++) { printf ("%i ", num & 0x01); num = num >> 1; } } I'm ...
WebChanging the n th bit to x. Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 or 1.
