ICS 103: Computer Programming in C Handout-16 Topic: 2-D Array Objective : To know what is 2-D array?  To know how to declare and reference 2-D array. To know how to read  and print  2-D array using for  loops. To know what is row-major  and column-major  order of 2-D array. What is 2_D Array ?  How to declare and  initialize  it ?: Just like single dimensional arrays we can have multidimensional arrays which are arrays of  arrays.  The two dimensional array can be visualized as a matrix. Consider the following two-dimensional array declarations  : #define SIZE 5 #define SIZE1 25 int grades [SIZE] [10] ; char letter [10] [4] ; float xyz [100] [SIZE1] ; The two-dimensional arrays need   two sizes   as name[m][n]. The total size of the array is the  product of the two sizes m x n . The  first  element is always name[0][0] and the  last   element is  name[m-1][n-1]. The two dimensional array elements are ordered by  row-wise   as name[0][0],  name[0][1], name[0][2]…, name[0][9], name[1][0], name[1][1],…, name[4][8], name[4][9]. The  two dimensional  array  elements are  ordered by   column-wise as name[0][0], name[1][0],  name[2][0]…, name[4][0], name[0][1], name[1][1],…, name[3][9], name[4][9]. In the first case, grades is an
