Web2.Multi-Dimensional Arrays. Two-Dimensional (2-D) Arrays. Multi-Dimensional Arrays comprise of elements that are themselves arrays. The simplest form of such arrays is a 2D array or Two-Dimensional Arrays. If an array has N rows and M columns then it will have NxM elements. 2-D Array Declaration is done as type array-name[rows][columns]. … WebOct 9, 2024 · Below are some of the different ways in which all elements of an array can be initialized to the same value: Initializer List: To initialize an array in C with the same value, the naive way is to provide an initializer list. We use this with small arrays. int num [5] = {1, 1, 1, 1, 1}; This will initialize the num array with value 1 at all index.
