numbers - finding values of x and y using Octal Base system -

in finding values of x , y , if (x567) + (2yx5) = (71yx) ( in base 8) proceeded under. i assumed x=abc , y=def , followed. (abc+010 def+101 110+abc 111+101)=(111 001 def abc) //adding ()+()=() , equating lhs=rhs. abc=111-010=101 5 in base 8 , def=001-101 -4 x=5 , y=-4 now question answer mentioned in book x=4 , y=3 . is above method correct.if so,then what's issue here ?? you can't compare digits beginning significant digit, because don't know carry digit below. digit cannot have negative value. you can start least significant digit, because there no carry: 7 + 5 = 14 so x = 4 carry of 1 @ next digit. can rewrite equation to: (4567) + (2y45) = (71y4) now can @ second least significant digit (the carry in mind): 6 + 4 + 1 (carry) = 13 so y = 3 , carry of 1. the whole equation is: (4567) + (2345) = (7134) which true octal system.

4 bit Binary Addition in C++ -

we given assignment make program takes 2 decimal numbers input , performs binary addition in background outputs decimal sum. seem getting wrong results despite how think code logic correct. my current sum gives me 0. correct answer should 24. #include <iostream> #include <sstream> #include <string> using namespace std; int add(int, int); int decbin(int); int bindec(long); int binadd(string, string); int main() { int = 15; int b = 9; int z; z = add(a,b); cout << z; return 0; } int add(int a, int b) { int z; ostringstream x, y; x << decbin(a); y << decbin(b); z = binadd(x.str(), y.str()); return z; } int decbin(int x) { int d[16]; int = 0; int j; int ans; while(x > 0) { d[i] = x % 2; i++; x = x / 2; } for(j = - 1; j >= 0; j--) { ans = d[j]; } return ans; } int bindec(int x) { int bin, dec = 0, rem, b

security - Safety of Self-signed certificate in a point-to-point socket with SSL -

-
i confirm understood using self-signed certificates if used point-to-point socket ssl. suppose have 1 client , 1 server. generate self-signed certificate , install certificate on both server , client. machines otherwise accept no other certificates. does mean in order mitm attacks, attacker must physically hack 1 of machines obtain certificate? what other vulnerabilities setup present if these 2 machines using certificate? thanks! yes, correct. in scenario describe, certificate used convenient way move public key machine. if configure client , server trust certificate, communication secure long can keep private key safe. other attack vectors exploiting other vulnerabilities in application or operating system runs in.

java - How to iterate HashMap without entrySet -

-
in original java source, must use entryset iterate hashmap, instance: (map.entry<string, string> e : new hash<string, string>().entryset()) { } i expect more simple way iterate hashmap following: package ro.ex; import java.util.hashmap; import java.util.map; /** * created roroco on 11/17/14. */ class hash<k, v> extends hashmap<k, v> { // how implement? } public class ex2 { public static void main(string[] args) { // expect (hash.entry<string, string > e : new hash<string, string>()) { } } } my question is how implement it? implement iterable<map.entry<k, v>> : class hash<k, v> extends hashmap<k, v> implements iterable<map.entry<k, v>> { @override public iterator<entry<k, v>> iterator() { return entryset().iterator(); } } this works because implementing iterable allows type used in for-each loop.
