Note that the declaration of the array type does not actually create the array, and the line: double[] inputValues; double av av=inputValues[0]; will cause a build error of: Use of unassigned local variable 'inputValues' As the array can not been created yet, and just contains a null value. 3.2.1 Initializing arrays The arrays when they are initialized are set to a default value, such as zero for numeric data types, and null for strings. To initialise it with actual values, the required values are contained within curly brackets, such as: int i[] = {10,20,30,40,50}; // First element i[0], Last element i[4] double[] vals = {1.2,1.4,1.6,1.8,2.0}; string[] menuItems = {"File", "Edit", "View", "Insert", "Tool", "Table"}; This performs both the declaration of the array and its initialization. Program 3.2 shows an example of the declaration of an array of strings. Program 3.2: Program3_2_ArrayInitializationStrings using System; duction to .NET Intro namespace ConsoleApplication2 { class ArrayExample01 { static void Main(string[] args) { int i; } } string[] ColourBands={"BLACK","BROWN","RED","ORANGE","YELLOW","GREEN"}; for (i=0;i
4 is YELLOW 5 is GREEN Program 3.3 uses an array of doubles which are initialized with certain values. It then uses a findSmallest() method to determine the lowest value. In this case the array (vals) is declared with seven elements (0 to 6). Program 3.3: Program3_3_ArrayInitializationNumeric using System; namespace ConsoleApplication2 { class ArrayExample01 { static double findSmallest(double[] v) { double smallest; smallest=v[0]; for (int i=1; i
