1. Arrays
2. Advantages and dis-advantages of arrays
An array is a collection of similar data types.
using System;
class Program
{
public static void Main()
{
// Initialize and assign values in different lines
int[] EvenNumbers = new int[3];
EvenNumbers[0] = 0;
EvenNumbers[1] = 2;
EvenNumbers[2] = 4;
// Initialize and assign values in the same line
int[] OddNumbers = { 1, 3, 5};
Console.WriteLine(“Printing EVEN Numbers”);
// Retrieve and print even numbers from the array
for (int i = 0; i < EvenNumbers.Length; i++)
{
Console.WriteLine(EvenNumbers[i]);
}
Console.WriteLine(“Printing ODD Numbers”);
// Retrieve and print odd numbers from the array
for (int i = 0; i < OddNumbers.Length; i++)
{
Console.WriteLine(OddNumbers[i]);
}
}
}
Advantages: Arrays are strongly typed.
Disadvantages: Arrays cannot grow in size once initialized. Have to rely on integral indices to store or retrieve items from the array.
