Ragged and Jagged Arrays
提问by Nitesh Verma
What is the difference between ragged and jagged arrays? As per my research both have the same definitions, i.e. two-dimensional arrays with different column lengths.
参差不齐的阵列和参差不齐的阵列有什么区别？根据我的研究，两者都有相同的定义，即具有不同列长度的二维数组。

Your question already says the correct answer ^^ but for completeness.
您的问题已经给出了正确答案 ^^ 但为了完整性。
A Jagged or also called Ragged array is a n-dimensional array that need not the be reactangular means:
锯齿状或也称为 Ragged 数组是一个 n 维数组，不需要是 reactangular 手段：
int[][] array = {{3, 4, 5}, {77, 50}};
回答by Bhupendra Shukla
Ragged array:is an array with more than one dimension each dimension has different size
参差不齐的数组：是一个多维数组，每个维度都有不同的大小
ex:
前任：
10 20 30
11 22 22 33 44
77 88
Jagged array:an array where each item in the array is another array. C# Code:
锯齿状数组：数组中的每一项都是另一个数组。C# 代码：
int[][] jaggedArray = new int[3][];
jaggedArray[0] = new int[5];
jaggedArray[1] = new int[4];
jaggedArray[2] = new int[2];

Jagged array is array of arrays such that member arrays can be of different sizes, i.e., we can create a 2-D arrays but with variable number of columns in each row. These type of arrays are also known as ragged arrays.
锯齿状数组是数组的数组，使得成员数组可以具有不同的大小，即我们可以创建一个二维数组，但每行的列数是可变的。这些类型的数组也称为不规则数组。

Ragged Array is also known as Jagged Array
锯齿状阵列也称为锯齿状阵列
1- A jagged array is non uniform array
1- 锯齿状数组是非均匀数组
2- Inner arrays can't be initialized so the following code snippet is going to fail
2- 无法初始化内部数组，因此以下代码片段将失败
double[][] jagged = new double[2][3]; //error
3- Instead each inner array is initialized separately
3- 而是分别初始化每个内部数组
double[][] jagged = new double[2][];
jagged[0] = new double[5];
jagged[1] = new double[7];
