这里直接使用string,不理解其中的用法,想着查缺补漏,便去找来《The C Programming Language》复习,在第5章“Pointers and Arrays”找到相关内容,便开始阅读起来,读完之后再回来看,发现代码后续的内容就是“Multidimensional array”,接着2.5节就是“Pointers and arrays”,
理论上,多维数组(Multidimensional Array)和数组的数组(Array of Arrays)是完全不同的概念。多维数组是一个真正的、在内存中连续存储的矩阵式结构,而数组的数组本质上是多个一维数组的嵌套。 在某些编程语言中(例如 C#),两者之间有着严格的区分。然而,在 C 语言中并不存在真正意义上的“多维数组”。我们看到的类似...
The use of this type will be illustrated in the section Passing a Multidimensional Array. We can also use array subscripts with pointers. Effectively, the notation pv[i] is evaluated as: *(pv + i) The pointer pv contains the address of a block of memory. The bracket notation will take ...
These variables can be assigned, be used as operands, and treated much the same as regular variables. Their use, however, can greatly simplify many of the truly difficult problems that arise in day-to-day programming. C supports multidimensional arrays. Programmers often find that much of the ...
The indirection operator (***) is applied after the last subscripted expression is evaluated, unless the final pointer value addresses an array type (see examples below). Expressions with multiple subscripts refer to elements of "multidimensional arrays." A multidimensional array is an array whose ...
C language permits the use of multidimensional arrays. It is easy to visualize arrays up to three dimensions. However, we may have difficulty in visualizing a four, five or in general, an n-dimensional array.
C Multidimensional Arrays ❮ Previous Next ❯ Multidimensional ArraysIn the previous chapter, you learned about arrays, which is also known as single dimension arrays. These are great, and something you will use a lot while programming in C. However, if you want to store data as a tabular...
We have also initialized the multidimensional array with some integer values. As I said earlier, a 3D array is an array of 2D arrays. I have divided elements accordingly for easy understanding. Looking at the C code sample above, In lines 9-13, 14-18, and 19-23, each block is a 2D...
