Here is an example of the multi-dimensional arrays in C++ that will explain you the things in deep: in the form of rows and columns. The following are the examples of creating two or three-dimensional arrays in c# programming language. In the code above we have declared a multidimensional integer array named “arr” which can hold 3x3x3 (or 27) elements. Data in multidimensional arrays are stored in tabular form (in row major order). 2: Passing arrays to functions. For example, following program fails in compilation because two dimensions are not specified. C++ Multi-Dimensional Arrays.

C supports multidimensional arrays. How to make a two-dimensional array. C language allows multidimensional arrays to be passed as actual arguments to a function. Write a C program to count total number of even and odd elements in an array. In C and C++ arrays do not support the size function, so programmers often have to declare separate variable to hold the size, and pass it to procedures as a separate parameter. // Two Dimensional Array. It is only restricted by memory usage, the amount of memory needed for an array can rapidly increase with each dimension you add. You will learn to declare, initialize and access elements of an array with the help of examples. This array returns the element sequentially.
