This post is an extension of How to dynamically allocate a 2D array in C? If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut. Recall that 2-D arrays are stored in row-major order i.e first row 0 is stored, then next to it row 1 is stored and so on. When speaking of arrays then arrays are pointers and passing array reference is actually passing array pointer. C Programming - Passing a multi-dimensional array to a function Posted on March 27, 2019 by Paul . In C programming, you can create an array of arrays. The second index must be given i.e. jagged arrays. For Static Array. how to return a 2-D array. The array can hold 12 elements. I have written a lot of articles on array and pointer if you want you can see this link, C Tutorial.Nowadays many students ask me a question that how to access a multidimensional array with a pointer in C or access two dimensional array using pointers in C I have replied many students but every month I found this question in my Inbox. Two-Dimensional Arrays in C. A two dimensional array (will be written 2-D hereafter) can be imagined as a matrix or table of rows and columns or as an array of one dimensional arrays. It's quick & easy. The catch for me was not the algorithm or rotation of array but to “pass the 2-D array in a function”. 2D Array is considered to be one of the simplest form under the multidimensional array. support true 2D arrays. Conclusion. Example. The 2D array is organized as matrices which can be represented as the collection of rows and columns. • Array indices must be of type int and can be a literal, variable, or expression.
