Now, if I'm still inside main and I set int i = sizeof(arr)/sizeof(arr[0]) then I is set to be 5, but if I pass the array as a function parameter and do the exact same calculation in this function, I get a different number. Why is that? At first I thought its because in a function arr is a pointer, but as far as I know arr is a pointer inside main too! Also, if I do something very similar only I initialize the array dynamically, I get weird results: int

For this task, speed is paramount. The size of the array will not be known until the data is imported, and may be very small (100 values) or enormous (10 million values). For the latter case, the code works fine, however I am encountering an error when I use fewer than 130036 array values. Does anyone know what is causing this issue and how to resolve it? I have attached the (tested) code involved, which

Any help is appreciated, thanks. 回答1: Use Overloaded Arrays#Sort(T[] a, Comparator c) which takes Comparator as the second argument. double[][] array= { {1, 5}, {13, 1.55}, {12, 100.6}, {12.1, .85} }; java.util.Arrays.sort(array, new java.util.Comparator (

This is a review for my test on thursday, and I have no idea how to approach this problem. 回答1: Also take a look at related sorts too: pigeonhole sort or counting sort , as well as radix sort as mentioned by Pukku. 回答2: Have a look at radix sort . 回答3: When people say "sorting algorithm" they often are referring to "comparison sorting algorithm", which is any algorithm that only depends on being able to ask "is this thing bigger or smaller than

Some objects in the array have a orderNum property which I am targeting to sort. But not all objects have this property. I want the objects with the orderNum property to be sorted to the top positions in the array.

A VBO is linked to a VAO via a call to glVertexAttribPointer(), where information about the VBO (buffer object name? Memory address?) is stored in the VAO. The VAO becomes available for update and drawing when it is bound via glBindVertexArray(). Does GL recompute the VBO address at that time? The VAO may or may not be bound when a VBO it links to gets updated via
