I\'m writing an application that uses Dijkstra algorithm to find minimal paths in the graph. The weights of the nodes and edges in the graph are float numbers, so the algorithm doing many arithmetics
Why does using a primitive data type work in the second \"for-each\" loop when I am looping over an array of objects. Is there a casting back to the primitive equivalent of the Integer object occurrin
In my C# source code I may have declared integers as: int i = 5; or Int32 i = 5; In the currently prevalent 32-bit world they are equivalent. However, as we move into a 64-bit world, am I correc
Maybe this question is easy,but I can\'t understand now. String.prototype.self=function() { return this;
I\'m pretty new to xna development and want to position the Cubes from the Primitives3D sample by passing a position vector to the constructor .. unfortunatly it does not work .. instead it is just sp
I have some classes that need a bunch of data tables to do their work (basically arrays of primitives, byte[], short[], int[] and float[]).
Why to use primitive types in java instead of Wrapper classes? I want to know that already we have wrapper classes in java, then why we need to use primitive types? What are the imp开发者_如何学编程or
If I have this in my .h file: int index; And then in the .m file I have: if (index == nil) and I haven\'t assigned a value to index, will that come up true?
I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance.
In C++ we can make primitives unsigned. But they are always positive. Is there also a way to make unsigned negative variables? I know the word 开发者_开发百科unsigned means \"without sign\", so also n
