Those two behave entirely differently. What does the letter 'u' mean in /dev/urandom? that makes it 0x0000000F, right?" 0xF == 0x0F == 0x00F == 0x000F ... == 0x0000000F == 0x0000000000000000000000000000000000000000000000000F on all machines. –Jim Balter Sep 13 '12 at 3:17 | show 2 more But the break sequence didn't work.
Yes: Random number: | 1001 0101 0xF | 0000 1111 Result: | 0000 0101 Nov 7, 2009 at 11:11pm UTC chrisname (7398) Oh; no wonder they use hex for low level Tt changes every 0 to 1 and every 1 to 0 in the binary representation.

raymond Jan 28, 2015 3:02 PM (in response to Learner) apologies, Just did some more digging, i dont think you can change the config register setting on a switch. The boot field determines if the router boots manually, from ROM, or from Flash orthe network. sizeof(char)? 0xf1 To Decimal It gives it in bytes.
Would this be considered as plagiarism? 0xf Config Register Browse other questions tagged c operators or ask your own question. Re: What is 0xF on a switch? here No new replies allowed.

It follows: 0 | 0 = 0 0 | 1 = 1 1 | 0 = 1 1 | 1 = 1 ^ means bitwise XOR operation. http://p2pgsm.com/to-decimal/0xfffffff-to-decimal.html current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list.
is an integer so it will contain 2*sizeof(int) digits Just realised this works only if CHAR_BIT == 8, the right formula is sizeof(int)*16/CHAR_BIT Anyway, who uses non 8-bit bytes any more? 0xf0 To Decimal Where is this useful? Since you're using 32 bits, the F's are just extended all the way out. 1111 .... 0000 For your second question, you're using a logical AND, not a bitwise AND.
Learner Jan 27, 2015 8:27 PM (in response to AICCOID22122009) Hi Sub,From your link to Scott Morris' answer:Just means those are default...2xxx means default to ROM software if normal boot failsx1xx We often try new types of ads in a limited capacity. Hi Raymond,I just tried password recovery on a 2960 switch that has the register 0xF. 0xff In Binary Because F is the largest Hex value?
