/* Problem 1 */ using System; using System.Collections; class Program { static void Main() { string[] names = new string[10]; Console.WriteLine(Please enter the names of 10 candidates
); for(int i = 1; i { Console.Write( {02} :  i); names[i - 1] = Console.ReadLine(); } Array.Sort(names new CaseInsensitiveComparer()); Console.WriteLine(
The candidates in alphabetical order are
); for(int i = 1; i { Console.WriteLine( {02} : {1} i names[i - 1]); } Console.ReadKey(); } } /* Problem 2 */ using System; class Program { static void Main() { Console.Write(Please enter the size of the identity matrix : ); int n = int.Parse(Console.ReadLine()); Console.WriteLine(
OK here it is
); int oneCol = 1; for(int i = 1; i { for(int j = 1; j { if (j == oneCol) Console.Write( 1); else Console.Write( 0); } Console.WriteLine(); oneCol++; } Console.ReadKey(); } } /* Problem 3 */ using System; class Program { static void Main() { Console.WriteLine(Please enter the elements of the first 2 x 2 matrix
); double[] a = FillMatrix(); Console.WriteLine(
Please enter the elements of the second 2 x 2 matrix
); double[] b = FillMatrix(); double[] c = MatrixMultiply(a b); Console.WriteLine(
The product of these matrices is
); for(int i = 1; i { for(int j = 1; j { Console.Write({0 4} c[i- 1 j-1]); } Console.WriteLine(); } Console.ReadKey(); } static double[] FillMatrix() { double[] m = new double[2 2]; for(int i = 1; i { for(int j = 1; j { Console.Write(Row {0} Col {1} :  i j); m[i - 1 j - 1] = double.Parse(Console.ReadLine()); } } return m; } static double[] MatrixMultiply(double[] m1 double[] m2) { double[] m3 = new double[2 2]; m3[00] = m1[00] * m2[00] + m1[01] * m2[10]; m3[01] = m1[00] * m2[01] + m1[01] * m2[11]; m3[10] = m1[10] * m2[00] + m1[11] * m2[10]; m3[11] = m1[10] * m2[01] + m1[11] * m2[11]; return m3; } }
