Note: In arrays, if the size of an array is N. The above example represents the element present in the third row and second column. In the above example, there is a total of three rows so there are three sets of inner braces.Īccessing Elements of Two-Dimensional Arrays: Elements in Two-Dimensional arrays are accessed using the row indexes and column indexes. Each set of inner braces represents one row. This type of initialization makes use of nested braces. Initializing Two – Dimensional Arrays: There are two ways in which a Two-Dimensional array can be initialized. A two – dimensional array ‘x’ with 3 rows and 3 columns is shown below: A two – dimensional array can be seen as a table with ‘x’ rows and ‘y’ columns where the row number ranges from 0 to (x-1) and column number ranges from 0 to (y-1).Elements in two-dimensional arrays are commonly referred to by x where i is the row number and ‘j’ is the column number.We can declare a two-dimensional integer array say ‘x’ of size 10,20 as:.The basic form of declaring a two-dimensional array of size x, y:ĭata_type array_name data_type: Type of data to be stored.We can see a two – dimensional array as an array of one – dimensional array for easier understanding. Two – dimensional array is the simplest form of a multidimensional array. Similarly array int x can store total (5*10*20) = 1000 elements. The array int x can store total (10*20) = 200 elements. The total number of elements that can be stored in a multidimensional array can be calculated by multiplying the size of all the dimensions. ISRO CS Syllabus for Scientist/Engineer Exam.
