I make a program to create an array with the range of my hero :
public function surface($fighterId,$porte_max,$porte_min){
$porte = $porte_max;
$longeur = 0;
$surface;
$i =0;
$coordonne_x=$this->findById($fighterId, array('field'=>'coordinate_x'));
$coordonne_y=$this->findById($fighterId, array('field'=>'coordinate_y'));
for( $for = ($coordonne_y['Fighter']['coordinate_y'] - $porte) ; ($coordonne_y['Fighter']['coordinate_y'] + $porte) ; $for++)
{
for( $for2 = ( $coordonne_x['Fighter']['coordinate_x'] - $longeur) ; ($coordonne_x['Fighter']['coordinate_x'] + $longeur) ; $for2++)
{
$surface[$i] = '[' . $for . '|' . $for2 . ']';
$i++;
}
if ($longeur < $porte)
{
$longeur++ ;
}
else $longeur-- ;
}
return $surface;
}
I don't understand the error:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes) in /var/www/html/WebArenaGroupSI4-02-AF/app/Model/Fighter.php on line 36
This is the issue with PHP memory has been exhausted. You can change your PHP memory limit in php.ini. Then restart your server.
Also your code has an endless for, the correct syntax for a for statement is like the following
for(initializationvalue , conditions, updatevalue){
// do your thing here
}
But in your condition, you did not put any conditions but instead did calculation in that.

I am having an error saying that prototype not terminated at filename.txt line number 113 where as line number 113 belongs to a different program which is running successfully.
sub howmany(
my #H = #_;
my $m = 0;
foreach $x (#H) {
if ( $x > 5 ) {
$m +=1;
}
else {
$m +=0;
}
}
print "Number of elements greater than 5 is equal to: $m \n";
}
howmany(1,6,9);
The sub keyword should be followed by { } not ( ) (if you define a simple function), that's why the error
prototype not terminated
After this, always start with : use strict; use warnings;
Put this and debug your script, there's more errors.
Last but not least, indent your code properly, using an editor with syntax highlighting, you will save many time debugging
The error is due to parenthesis.
Never do $m += 0; As you actually load processor for nothing. Of course it's not gonna be visible on such a small function, but...
sub howmany {
my $m = 0;
foreach (#_) {
$m++ if ($_ > 5);
}
print "Number of elements greater than 5 is equal to: $m \n";
}
howmany(1,6,9);
I already have a program in java which works fine. I tried writing the same one in php and got to some errors.
For example, in this code
for ($i=0; $i<64; $i++) {
$r=$i/8;
$c=$i%8;
$temp=1;
for ($j=-1; $j<=1; $j+=2) {
for ($k=-1; $k<=1; $k+=2) {
while(" " == $chessBoard[$r+$temp*$j][$c+$temp*$k])
{
//some other code here
}
}
}
}
$chessBoard is a two dimensional array
$chessBoard= array
(
array("r","k","b","q","a","b","k","r"),
array("p","p","p","p","p","p","p","p"),
array("0","0","0","0","0","0","0","0"),
array("0","0","0","0","0","0","0","0"),
array("0","0","0","0","0","0","0","0"),
array("0","0","0","0","0","0","0","0"),
array("P","P","P","P","P","P","P","P"),
array("R","K","B","Q","A","B","K","R")
);
I know that the error happens when I'm trying to access $chessBoard[$r+$temp*$j][$c+$temp*$k] when for example $r is 0 and $j is -1, then I get 0+1*-1 which is -1, but I don't know how to get rid of this problem and still have the program to work properly. It's still not clear to me why I didn't have the same problem in java.
Before the code
while(" " == $chessBoard[$r+$temp*$j][$c+$temp*$k])
{
//some other code here
}
put in:
if($r+$temp*$j < 0 || $c+$temp*$k) continue;
This will go to the next iteration of the for-loop and will not run into any indexoutofboundsexception
I was recently dealing with a hash that I wanted to print in a nice manner.
To simplify, it is just n array with two fields a['name']="me", a['age']=77 and the data I want to print like key1:value1,key2:value2,... and end with a new line. That is:
name=me,age=77
Since it is not an array whose indices are autoincremented values, I do not know how to loop through them and know when I am processing the last one.
This is important because it allows to use a different separator on the case I am in the last one. Like this, a different character can be printed in this case (new line) instead of the one that is printed after the rest of the files (comma).
I ended up using a counter to compare to the length of the array:
awk 'BEGIN {a["name"]="me"; a["age"]=77;
n = length(a);
for (i in a) {
count++;
printf "%s=%s%s", i, a[i], (count<n?",":ORS)
}
}'
This works well. However, is there any other better way to handle this? I don't like the fact of adding an extra count++.
In general when you know the end point of the loop you put the OFS or ORS after each field:
for (i=1; i<=n; i++) {
printf "%s%s", $i, (i<n?OFS:ORS)
}
but if you don't then you put the OFS before the second and subsequent fields and print the ORS after the loop:
for (idx in array) {
printf "%s%s", (++i>1?OFS:""), array[idx]
}
print ""
I do like the:
n = length(array)
for (idx in array) {
printf "%s%s", array[idx], (++i<n?OFS:ORS)
}
idea to get the end of the loop too, but length(array) is gawk-specific and the resulting code isn't any more concise or efficient than the 2nd loop above:
$ cat tst.awk
BEGIN {
OFS = ","
array["name"] = "me"
array["age"] = 77
for (idx in array) {
printf "%s%s=%s", (++i>1?OFS:""), array[idx], idx
}
print ""
}
vs
$ cat tst.awk
BEGIN {
OFS = ","
array["name"] = "me"
array["age"] = 77
n = length(array) # or non-gawk: for (idx in array) n++
for (idx in array) {
printf "%s=%s%s", array[idx], idx, (++i<n?OFS:ORS)
}
}
Okay so this is my code
var no:int = 0;
var elem:int = 0;
loadedData = myLoader.data.split(/\r\n|\n|\r/);
for (var i:int = 0; i < loadedData.length; i++)
{
if (loadedData[i] != '')
{
if (loadedData[i] != ',')
{
if(patterns[no] == undefined) patterns[no] = [];
trace(no);
trace(elem);
obstacleData[i] = loadedData[i].split(",");
trace(patterns[no]);
patterns[no][elem] = obstacleData[i][0];
patterns[no][elem + 1] = obstacleData[i][1];
elem += 2;
trace('Pattern' , no, ': ', patterns[no]);
}
else if (loadedData[i] == ',')
{
no += 1;
elem = 0;
patterns[no] = 0;
}
}
}
The problem is at this line
patterns[no][elem] = obstacleData[i][0];
I'm getting the error: [Fault] exception, information=ReferenceError: Error #1056: Cannot create property 0 on Number.
I've read around on this and multidimensional arrays just seem to be so much more complicated on AS3 compared to other languages where you just create a multidimensional array and it works.
I feel like I've done something really obvious wrong and will feel like an idiot upon someone telling me but I really need help on this one since I'm new to this whole AS3 way of creating multidimensional arrays.
Just in case the output for the code when run is as so:
0
0
Pattern 0 : 300,60
0
2
300,60
Pattern 0 : 300,60,350,90
1
0
0 <--- This might be the problem?
[Fault] exception, information=ReferenceError: Error #1056: Cannot create property 0 on Number.
Maybe the error is caused by the line
patterns[no] = 0;
I think you want to assign an empty array or maybe null and check for null later.
I have a Perl-Script, which executes a recursive function. Within it compares two elements of a 2dimensional Array:
I call the routine with a 2D-Array "#data" and "0" as a starting value. First I load the parameters into a separate 2D-Array "#test"
Then I want to see, if the array contains only one Element --> Compare if the last Element == the first. And this is where the Error occurs: Modification of non creatable array value attempted, subscript -1.
You tried to make an array value spring into existence, and the subscript was probably negative, even counting from end of the array backwards.
This didn't help me much...I'm pretty sure it has to do with the if-clause "$counter-1". But I don't know what, hope you guys can help me!
routine(#data,0);
sub routine {
my #test #(2d-Array)
my $counter = $_[-1]
for(my $c=0; $_[$c] ne $_[-1]; $c++){
for (my $j=0; $j<13;$j++){ #Each element has 13 other elements
$test[$c][$j] = $_[$c][$j];
}
}
if ($test[$counter-1][1] eq $test[-1][1]{
$puffertime = $test[$counter][4];
}
else{
for (my $l=0; $l<=$counter;$l++){
$puffertime+= $test[$l][4]
}
}
}
#
#
#
if ($puffertime <90){
if($test[$counter][8]==0){
$counter++;
routine(#test,$counter);
}
else{ return (print"false");}
}
else{return (print "true");}
Weird thing is that I tried it out this morning, and it worked. After a short time of running he again came up with this error message. Might be that I didn't catch up a error constellation, which could happen by the dynamic database-entries.
Your routine() function would be easier to read if it starts off like this:
sub routine {
my #data = #_;
my $counter = pop(#data);
my #test;
for(my $c=0; $c <= $#data; $c++){
for (my $j=0; $j<13;$j++){ #Each element has 13 other elements
$test[$c][$j] = $data[$c][$j];
}
}
You can check to see if #data only has one element by doing scalar(#data) == 1 or $#data == 0. From your code snippet, I do not see why you need to copy the data to passed to routine() to #test. Seems superfluous. You can just as well skip all this copying if you are not going to modify any of the data passed to your routine.
Your next code might look like this:
if ($#test == 0) {
$puffertime = $test[0][4];
} else {
for (my $l=0; $l <= $counter; $l++) {
$puffertime += $test[$l][4];
}
}
But if your global variable $puffertime was initialized to zero then you can replace this code with:
for (my $l=0; $l <= $counter; $l++) {
$puffertime += $test[$l][4];
}
