Webint i = 512; i & 0xFF; // this gives me the first byte. That must mean i & 0xFF gives me the first byte that is stored in memory. In other words, i & 0xFF is the first of the four bytes i consists of stored at the lowest memory address. Next, I think that i << 8 & 0xFF will then shift everything left by 8 bits and giving me the second byte.

WebJan 1, 2024 · The most straightforward way of converting a byte array to a numeric value is using the shift operators. 2.1. Byte Array to int and long. When converting a byte array to an int value, we use the << (left shift) operator: int value = 0 ; for ( byte b : bytes) { value = (value << 8) + (b & 0xFF ); } Copy. http://andersk.mit.edu/gitweb/openssh.git/blobdiff/e62075983f11ef51d9586f304302bcfece42f63c..e3dde83406964a0a3e027af2c28f69b96c234f7d:/bufaux.c WebFeb 13, 2014 · The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes. Nowadays, it's most often 4 bytes on a 32-bit as well as 64-bit systems. Still, using sizeof (int) is the best way to get the size of an integer for the specific system the program is executed on. can be proved

They are basically packed arrays of small (byte-sized) integers (in the range 0-255, i.e. 8-bit data). They are memory-efficient, but if you actually want to interpret or manipulate the data (other than a simple …
