What is the best way to pass 2D arrays to a function? (C++) For my program, I have a 2D array (size: N by N) of some structs. I need to go through each element in the array and check its status, and change it if necessary. Because of this, I know I cannot pass it by value or else I wouldn't be able to change the values in the 2D array. But when passing it by reference, it usually has a type error or something. I am mostly confused on the syntax of the input parameters and how I should call the function. I have always had trouble with this in the past, and still don't really understand the standard/best way to do it. Would it be a pointer to the first [0][0] element? Please help, thanks! If you need more information just ask

To what is the term “base address of an array” refer, and how is it used in a function call?

I am designing a application which can generate a 2 d array which contains the random elements and print that generated matrix on the console. Take the size of matrix from the user. In python

There is a close association between pointers and arrays. Recall that an array variable is actually a pointer variable that points to the first indexed variable of the array. Array elements can be accessed using pointer notation as well as array notion. One problem with static arrays is that we must specify the size of the array when we write the program. This may cause two different problems: (1) we may create an array much larger than needed; or (2) we may create one that is smaller than what is needed. In general, this problem is created because we do not know the size of the array until the program is run. This is where dynamic arrays can be used. The new expression can be used to allocate an array on the freestore. Since array variables are pointer variables, you can use the new operator to create dynamic variables that are arrays and treat these dynamic array variables as if they were ordinary arrays. Array elements can also be accessed using pointer notation as well as array…
