WebMar 31, 2024 · Viewed 59 times. 1. I am trying to understand how dynamic allocation of a 2D array works internally in C++. While allocating memory dynamically for a 2D array of type int and size m * n, we write: int **arr = new int * [m]; and then run a loop across the size m until we reach the number of columns, n, allocating an array to each pointer. WebNote: Unlike C, C++ allows dynamic allocation of arrays at runtime without special calls like malloc (). If n=10, int arr [n] will create an array with space for 10 integers. Accessing elements of an array: Indexing in arrays starts from 0.So the first element is stored at arr[0],the second element at arr[1] and so on through arr[9] .
