was this a homework problem? Please don't post homework problems on the site. If we just give you the answer then what is the point of taking the class? If it wasn't homework then my apologies.

Try this: using System; class Test { static void Main() { string[] Array1 ={a sd fgh}; string[] Array2 = {c op}; string[] Array3 = new string[Array1.Length + Array2.Length]; Array.Copy(Array1 0 Array3 0 Array1.Length); Array.Copy(Array2 0 Array3 Array1.Length Array2.Length); int[] set = new int[]{0 1 2 3 4}; int[][] perm = new int[20][]; int count = 0; for(int i = 0; i for(int j = i + 1; j { perm[count++] = new int[]{set[i] set[j]}; perm[count++] = new int[]{set[j] set[i]}; } Console.WriteLine(The 20 possible permutations are :
); for(int i = 0 ; i { Console.WriteLine({03} : {1} i+1 Array3[perm[i][0]] + Array3[perm[i][1]]); } Console.ReadLine(); } }
