I see this in code sometimes: struct S { int count; // length of array in data int data[1]; }; Where the storage for S is allocated bigger than sizeof(S) so that data can have more space for its array. It is then used like: S *s; // allocation s->data[3] = 1337; My question is, why is data not a pointer? Why the length-1 ...

I have a python script that successfully loads a csv file into a 2d numpy array and which then successfully extracts the value of a desired cell based on its column and row header values. For diagnostic purposes, I have the script print the contents of the data matrix before it is put into a numpy array. The script works when the data ...

How do you add an value with an => $key into an array, for example: $images = array(); array_push($images, $_FILES['file']['tmp_name'] => $_FILES['file']['name']); So the array would be like: array('temporary_file_name' => 'file_name.zip'); But my IDE says it's invalid and would not work. ...

I'm learning Ruby, and have just gotten into some stuff about arrays and ranges. I've run into something about slices that, while it makes sense at first glance, confuses me a bit when i look deeper into it. irb says that (2..-1).to_a is an empty array. Meaning no values in the range, right? But if i use that same range in [:a, :b, :c...

What's the fastest way to get sum of all values? The reason I ask is cause this is a major bottleneck in a program I inherited. They a...

In my Windows Mobile (.NET Compact Framework) application I use a big array to store the application's primary data. This is a dataset of potentially hundreds of objects.

The problem I've just faced is what to do in the following case: func printItems(header string, items []interface{}, fmtString string) { // ... } func main() { var iarr = []int{1, 2, 3} var farr = []float{1.0, 2.0, 3.0} printItems("Integer array:", iarr, "") printItems("Float array:", farr, "") } Go has no generics and does...
Is there a function in javascript to do this - test if a given value (a string in my case) exists in an array (of strings)? I know I could just loop over each value, but I'm wondering if js has a shorthand for this. ...
Hi. consider the following code: void Increment(int *arr) { arr++; } int main() { int arr[] = {1,2,3,4,5}; // arr++ // illegal because its a const pointer Increment(arr); // legal } My question is if arr is a const pointer, how come i can send it to a function that doesn't receive a const pointer? The code compile...
