I'd like to be sure about how exactly an SQL index will work in this particular situation, so please share your thoughts.

Wow. Clearly I overlooked something quite elementary. Enclosing $1 in quotes prevents using the asterisk as a wildcard:
math(){
echo "$1" | bc -l
}Don't you hate when you try for hours to fix...
I'm writing a shell script in which I am performing floating point calculations. I cannot use `expr` since it does not support real numbers, so I decided to write/use a function to use `bc` like...
To explain precisely what would occur with your proposed code (assuming you were able to correct it for successful compilation), the foo() function would create a pointer variable 'p' which you point...
Sorry Hairy, but your answer isn't valid. I actually browsed Google's validation code (JavaScript) and it basically does this to check your submission: if ((24 - your_answer) < 0.0001) you_win();...
Actually, working (both from employment and marriage) and not partying (unfortunately). I already have a full-time job and have been here for 9 years as of next month. As a result of graduating, I...
I just wanted to take this opportunity to share my glee by announcing that I have finally graduated with my Bachelor's of Science degree in Computer Science (with honors, btw ;)). It took me 10 long...
At first I was mildly entertained with my initial attempts to solve Google's current puzzle, but after dozens of attempts I became feverishly determined to solve it. I finally decided to screw my...
Well, friends... The end is extremely f___ing nigh: I am graduating from my university with a B.S. in Computer Science with honors (I have to mention the "with honors" part because I just found that...
The epsilon represents nothing. In other words a regular expression like ab?c could be accpeted by a grammar like:
S -> aTc
T -> b | epsilon
In any case, I have found the problem, and it...
I'm suffering a problem with a yacc specification. I had a similar problem but was able to resolve it. I'm sure the problem is in the recursion madness I'm dealing with, but am unable to find a clear...
You must use the scope resolution operator (::) instead of the dot operator, which is used to reference members of an object.
cout << "gaurav " << hello::val;Also, you must declare static member...
I've an Associate of Arts degree in Liberal Arts, an Associate of Science degree in Computer Science, and I'll receive my Bachelor of Science degree in Computer Science with emphasis in systems...
I have an acquaintance in France who was hired on to a professional gaming company based largely on a single game he wrote from scratch. I don't know his previous achievements, but when I spoke with...
Scrabble. Now there's a fun challenge. In addition to forming words (obviously, they'd come from a dictionary of valid terms), you need to use as many letters as possible, attempt to acquire as many...
I was walking around a Japanese market/shopping center with my wife last week and we were shocked when we found a plastic container with four apples in it, or so we thought. The label on the...
Just within the box, rows, and columns. Diagonally wouldn't make sense because there are only two diagonals with 9 cells.
Every complete puzzle, of which there are billions of trillions, has...
Su Doku is a puzzle. It consists of nine boxes composed of nine cells. Each box has each digit from 1 to 9. Each puzzle-wide row and column (spanning three boxes) has each digit from 1 to 9. This...
Try using Borland's command-line compiler (in the second table on that linked page named "Compiler"). It is free and works very well, but you may not be too keen on it because the free version...
I think a brief explanation of ASCII is warranted here. You, Bag a Bones, seem to be confusing keyboard values for ASCII values. What you must keep in mind is that ASCII is simply a standard that...
Try something like this, adjusting the dereferencing et cetra to match your actual variables. This should work assuming you are attempting assignment.
LONG smaller = *(LONG*)&bigger;
I know this is an old thread, but I just found it and felt like implementing my own solution.
#include <iostream>
using namespace std;
...
Search the string for the current locale's integer and decimal separator. (You're splitting hairs, CornedBeef. In a real situation that might present a serious concern, but our friend is surely...
A less elegant, yet highly precise solution would have you simply convert the resultant value to a string and analyze that.
bool is_sqrt_int(double your_value) {
std::ostringstream ostr;
