2014年2月13日 · Does an Integer variable in C occupy 2 bytes or 4 bytes? What are the factors that it depends on? Most of the textbooks say integer variables occupy 2 bytes. But when I run a program printing the

2018年1月4日 · I am trying to read a 2-byte value that is stored lower order byte first. So if the 2 bytes are 10 and 85 in that order (decimal) what is the number they represent? 8510? 851? Or something different? These values represent the length of an encoded sequence and I need to know the length to properly handle the information it contains.

2014年11月5日 · I'd say you're wrong. 1 byte size of 8 bits can hold a single 8 bit character, hence 2 bytes can hold two 8 bit characters. If you mean numbers, with two bytes the range is 0 - 65535.

Your confusion stems from the fact that you're trying to count bits (8 bits in one byte) and then use what they represent (8 bits represents up to (2^8)-1) to measure increasing size. Ergo, twice 8 bits is 16 bits. Twice what 8 bits can represent is 9 bits.

2012年7月30日 · That's why you get 2-byte (short), 4-byte (int) and 8-byte (long long) numbers. In truth, if you need even higher range of numbers, you would need to use a library.

A two-byte number has a low and a high byte. The high byte is worth 256 times as much as the low byte: value = 256 * high + low; So, for high=0 and low=7, the value is 7. But for high=7 and low=0, the value becomes 1792. This of course assumes that the number is a simple 16-bit integer. If it's anything fancier, the above won't be enough. Then you need more knowledge about how the number is ...

2015年1月21日 · A word in our case is 4 bytes, or 32 bits. So our 5 byte buffer is really going to take 8 bytes (2 words) of memory, and our 10 byte buffer is going to take 12 bytes (3 words) of memory.

2013年6月12日 · I receive a port number as 2 bytes (least significant byte first) and I want to convert it into an integer so that I can work with it. I've made this: char buf[2]; //Where the received bytes are ...

2016年9月7日 · So if we have 2^13 bits and want to convert it to bytes then 2^13 bits = x * 1Byte / (2^3 bits) = 2^10 bytes which is a kilobyte. Now with this conversion, it makes much more sense to me why they choose to represent Bytes in powers of 2.

2015年8月31日 · This table tells you that the low byte value describes values between 0,0039 (the first bit in the byte) and 0,5 (the last bit in the byte). Combined it is close to 1, the first bit in the high byte. The highest value is 128, which is the sixth bit of the high byte. The seventh bit tells you if the number is negative or positive. So this is a signed integer of 8 bits with some extra precision.
