Although an array might be declared to have so many elements that does not always mean that all of the cells in the array actually have meangingful data Sometimes a program does not know how much data it will read in from a le or external source so it declares an array much larger than it needs Then after it
Two-Dimensional Arrays Arrays that we have consider up to now are one-dimensional arrays a single line of elements Often data come naturally in the form of a table e g spreadsheet which need a two-dimensional array Examples: Lab book of multiple readings over several days Periodic table Movie ratings by multiple reviewers
turn an array of a speci?c size the user has no way of knowing how many elements in the array can be accessed safely without exceeding its bounds Without such a corresponding postcondition code calling fib(10) could not even safely access position 0 of the array that fib(10) returns
Two-dimensional array is nothing but extension of one-dimensional array. Like array, it holds some same type of data element in a different manner. It holds all the properties as single dimension array has. Now, we see how two-dimensional arrays are declared in a C programming. One array called has two blocks.
We can calculate how many elements a two dimensional array can have by using this formula: The array arr [n1] [n2] can have n1*n2 elements. The array that we have in the example below is having the dimensions 5 and 4. These dimensions are known as subscripts. So this array has first subscript value as 5 and second subscript value as 4.
• Two-dimensional (2D) arrays are indexed by two subscripts, one for the row and one for the column. • Example: row col rating[0][2] = 2! !rating[1][3] = 8! • either a primitive type or object type.
