Find and fix the bugs in a two-dimensional array in C#

/* This program computes the average of a student's grades. The expected output is: The smallest value is 1 The program has a syntax error (wrongly coded), a specification error (wrongly implemented), and a semantic error (wrong logic). Discuss with the instructor what each of the errors is and why they are wrong. After a response, fix the specification and semantic errors and test to ensure that the program is working as expected. */ using System; namespace IDL2 { public class smallest { public static void Main(string[] args) { int[,] matrix = { {2, 6, 9}, {4, 4, 9}, {6, 3, 8}, {4, 7, 1} }; int small = 0; for (int i = 0; i < matrix.GetLength(0), ++i) for (int j = 0; j < matrix.GetLength(0); ++j) if (matrix[i,j] < small) small = matrix[i,j]; Console.WriteLine("The smallest value is " + small); } } }
