How to format numbers as currency string?
...ode with a bit of comments added and some minor changes:
/*
decimal_sep: character used as deciaml separtor, it defaults to '.' when omitted
thousands_sep: char used as thousands separator, it defaults to ',' when omitted
*/
Number.prototype.toMoney = function(decimals, decimal_sep, thousands_sep)...
Return array in a function
...llarr(int arr[]){
array[0] = 10;
array[1] = 5;
}
int main(int argc, char* argv[]){
int arr[] = { 1,2,3,4,5 };
// arr[0] == 1
// arr[1] == 2 etc
int result = fillarr(arr);
// arr[0] == 10
// arr[1] == 5
return 0;
}
I suggest you might want to consider putting a leng...
What is the point of the diamond operator () in Java 7?
...de by saving repeated type arguments. In practice, it's just two confusing chars more giving you nothing. Why?
No sane programmer uses raw types in new code. So the compiler could simply assume that by writing no type arguments you want it to infer them.
The diamond operator provides no type infor...
Samples of Scala and Java code where Scala code looks simpler/has fewer lines?
...rds (like books).
Explanation:
Input: List<String>
Output: Map<Character, List<String>>
The key of map is 'A' to 'Z'
Each list in the map are sorted.
Java:
import java.util.*;
class Main {
public static void main(String[] args) {
List<String> keywords = Arrays.as...
Why don't structs support inheritance?
...like:
for (int i = 0; i < values.Length; ++i)
{
A* value = (A*) (((char*) values) + i * sizeof(A));
value->A *= 2;
}
(Yes, that's abominable assembly, but the point is that we'll increment through the array at known compile-time constants, without any knowledge that a derived type i...
Default implementation for Object.GetHashCode()
...sually more interested in whether a string containing the same sequence of characters has already been added. That's why string overrides GetHashCode. On the other hand, suppose you want to keep a count of how many times various controls process Paint events. You could use a Dictionary<Object,...
What's the difference between ASCII and Unicode?
...
ASCII defines 128 characters, which map to the numbers 0–127. Unicode defines (less than) 221 characters, which, similarly, map to numbers 0–221 (though not all numbers are currently assigned, and some are reserved).
Unicode is a superset...
How can I output a UTF-8 CSV in PHP that Excel will read properly?
...pen this file in TextEdit or TextMate or Dreamweaver and it displays UTF-8 characters properly, but if I open it in Excel it's doing this silly íÄ kind of thing instead. Here's what I've got at the head of my document:

How I can I lazily read multiple JSON values from a file/stream in Python?

e.args[0]).groups()[0])
json_str = f.read(end_pos)
obj = json.loads(json_str)

Does Java have something like C#'s ref and out keywords?
...his should be expanded on some. You can only pass primitives (int, short, char, etc.) as value. And no, there is no out.
