input from user to know pattern of movement.
Nov 10 2013 10:38 AM
Good evening teacher. I was trying to get the program to tell me how the king moved. But i believe there is a better and effective way of writing the code. Please kindly take a look at it and trim it how possible or a better way of thought in writing it. Thanks.
{
string[] a = {"A","B","C","D","E","F","G","H"};
string pos;
int posI;
int posS = 1;
string pos2;
int pos2I;
int pos2S = 1;
string Step = "";
int steps = 0;
do
{
Console.WriteLine("Enter position of the king A-H 1-8: ");
pos = Console.ReadLine().ToUpper();
}
while (pos.Length != 2 ||
!(pos[0] >= 'A' && pos[0] <= 'H') ||
!(pos[1] >= '1' && pos[1] <= '8'));
{
Console.WriteLine("You entered {0}", pos);
posI = int.Parse(pos[1].ToString());
}
for (int i = 0; i < 8; i++)
{
if (a[i] == pos[0].ToString())
{
posS = i + 1;
}
}
do
{
Console.WriteLine("Enter position where the king need to be A-H 1-8: ");
pos2 = Console.ReadLine().ToUpper();
}
while (pos2.Length != 2 ||
!(pos2[0] >= 'A' && pos2[0] <= 'H') ||
!(pos2[1] >= '1' && pos2[1] <= '8'));
{
Console.WriteLine("You entered {0}", pos2);
pos2I = int.Parse(pos2[1].ToString());
}
for (int j = 0; j < 8; j++)
{
if (a[j] == pos2[0].ToString())
{
pos2S = j + 1;
