c - convert a pointer of array in Java -

-

i'm trying convert program in c java. don't know c programming, i'd understand bit btw.

well i've got functions in c:

static int memcmp( byte *a, byte *b, int len) {     int i;     (i = 0; < len; i++)          if (a[i] != b[i])              return 0;     return 1; }  static int rfind(byte *data, int pos, int leng) {     int i;     (i = pos - leng; > -1; i--)          if (memcmp(data+i, data+pos, leng))              return i;     return pos; }

that can't workout. seems function memcmp compare 2 blocks of memory. when size of data:

printf("size %d \n", sizeof(data));

i got 8 result while orignal size can 32 or 40 (any documentation pointers welcome).

anyone me translate bit java have gratitude (and more). thanks

java doesn't have pointers, can't translate code directly. in c, can treat pointers arrays, whereas in java need use indexes same array. more or less direct translation can come with:

public int rfind(byte[] data, int pos, int len) {     (int = pos - len; > -1; i--) {         if (memcmp(data, i, pos, len)) {             return i;         }     }     return pos; }  public boolean memcmp(byte[] data, int idx1, int idx2, int len) {     (int = idx1; <= len; i++) {         if (data[i] != data[idx2 + i]) {             return false;         }     }     return true; }

edit

as ayush points out, if data array ascii string, can same result in simple way using library calls.

string str = new string(data); // convert data byte array string string sub = str.substring(pos, len); // substring pointed pos int rfindresult = str.lastindexof(sub);

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
