Double jagged array

Question

can double jagged array has dynamic ? how?

It depends what you mean by 'dynamic'. In C# once you create an array it's size cannot be changed. Methods such as Array.Resize actually create a new array of the required size and copy the elements of the old array to it. A 'jagged array' is essentially an array of arrays and unlike a rectangular array the size of the constituent arrays need not be the same. However once they've been created the size of the constituent arrays cannot be changed. For example: double[][] array = new double[2][]; creates a jagged array with 2 array elements. Each of those array elements can now be individually set: array[0] = new double[2]; array[1] = new double[3]; They can also be changed to different arrays including at runtime: int i = 4; array[0] = new double[i]; but there's no way in which the current array assigned to array[0] can have its size changed. If you want something that can dynamically change its size as new elements are added then use a List > rather than a jagged array of doubles.
