I have this while loop in xcode. The loop seems to work fine since I printed my i++ in console. But for some reason it only checks my IF statement the first time around. I can only add one title into the MutableArray called sectionZeroTitleArray. I have many arrays in this loop so it might get confusing. I will try my best to explain. ...
I'm using a slider so that users can select their place in a range from 1-10 (or a similar range) I know that i can specify the values/steps for the slider but can i have those values correspond to another? i.e. 1 = id3040 2 = id0290 3 = id3782 So if they select '3' on the slider, I can get that corresponding value? I have a surve...
I have a 2-d array xx=[[a,1],[b,2],[c,3]] Now I'm trying to remove duplicate entries from it. For simple 1-D array, simple code like xx=list(set(xx)) would work. But trying set on 2-d elements gives an error temp = set(xx) TypeError: unhashable type: 'list' One workaround would be to serialize xx elements, and then do a list(se...
In one of my scripts, I try to do the following $data[] = self::get($row['sr_id']); // <-- line 55 However, PHP does not allow me to do this, giving me this error Fatal error: Cannot use [] for reading in /file.php on line 55 The self::get function return either a bool, or an object.

From my lecture slides, it states: As illustrated in the code below an array name can be assigned to an appropriate pointer without the need for a preceding & operator. int x; int a[3] = {0,1,2}; int *pa = a; x = *pa; x = *(pa + 1); x = *(pa + 2); a += 2; /* invalid */ Why is a += 2; invalid? Can anyone help clarify...

Question asks itself ^ I've heard I can mimic this using http_build_query, but I'd rather use a function that's meant for this. Thanks for replies input example: $assoc = array( "fruit" => "banana", "berry" => "blurberry", "vegetable" => "lettice" ); output wanted: (i get this with http_build_query) string(46) "fruit...

Hi I have a matrix file that is 32X48 and I want to put all of the values into a single dimensional array in R. Right now I am only able to get the last row of data. trgtFN_intensity <- "1074_B09_1- 4_5mM_Xgal_7d_W.cropped.resized.grey.png.red.median.colony.txt"; read.table(trgtFN_intensity, sep="\t") -> tmp_int maxrow_int <- nrow(...
Hi, I have a C function in which I have 4 pointers and each of them point to different locations of a large 2D array of floats. Because the ARM assembly functions can only be passed with 4 parameters (r0 - r3), I'm not able to understand how to pass the pointer to my return value, which will become the 5th parameter to my assembly func...

I want to return an array each element having an int and two...

What I'm doing is making it possible to declare multiple "virtual screens", with dimensions of the programmer's choice. For this, I need to dynamically allocate enough memory based on the number of pixels the screen will c...
