C# 배열

[C#] 다차원 배열, 가변 배열

1. 다차원 배열 using System; clss Program { static void Main() { int[] arr = new int[3]; int[,] arr1 = new int[3, 2]; int[,] arr2 = new int[3, 2] {{1, 1}, {2, 2}, {3, 3}}; int[,] arr3 = new int[,] {{1, 1}, {2, 2}, {3, 3}}; int[,] arr4 = {{1, 1}, {2,2}, {3,3}}; arr1[0, 0] = 10; arr1[0, 1] = 20; foreach(int n in arr2) Console.WriteLine(n); int[,,] arr5 = new int[2, 2, 2]; int[,,,] arr6 = new int[2, 2, ..

[C#] 배열 기본

1. 핵심 정리 using System; class Program { int[] arr1; int[] arr2 = new int[5]; int[] arr3 = new int[5] {1, 2, 3, 4, 5}; int[] arr4 = new int[] {1, 2, 3, 4, 5}; int[] arr5 = {1, 2, 3, 4, 5}; Type t = arr5.GetType(); Console.WriteLine(t.FullName); Console.WriteLine(arr5.Length); // 5 Console.WriteLine(arr5.GetLength(0)); // 5 Console.WriteLine(arr5.GetValue(3)); // 4 Console.WriteLine(arr5.GetLowerBo..
