Logic for custom number system...

Question

I need to create a logic that works for a number system..

means if A=1, B=2, C=3, D=4,E=5, F=6; G=7,H=8,I=9, O=0;

if i give input as A+B, then result should be come as C, not 3,

or if i give F+G then output should be AC;

if any one have some idea about it,, post that..

Try this: using System; public static class CustomNumber { private static char DigitToSymbol(char digit) { if (digit >= 49 && digit return 'O'; } private static char SymbolToDigit(char symbol) { if (symbol >= 65 && symbol if (symbol == 'O') return '0'; throw new ArgumentException(symbol +  is not a valid symbol); } public static string Calculate(string op) { string[] items = op.Split('+'); if (items.Length != 2) throw new ArgumentException(op +  is not a valid operation); string operand1 = items[0].Trim(); string operand2 = items[1].Trim(); char[] digits1 = new char[operand1.Length]; char[] digits2 = new char[operand2.Length]; for(int i = 0; i { digits1[i] = SymbolToDigit(operand1[i]); } for(int i = 0; i { digits2[i] = SymbolToDigit(operand2[i]); } int number1 = int.Parse(new string(digits1)); int number2 = int.Parse(new string(digits2)); string sum = (number1 + number2).ToString(); char[] symbols = new char[sum.Length]; for(int i = 0; i { symbols[i] = DigitToSymbol(sum[i]); } return new string(symbols); } } class Program { static void Main() { string sum = CustomNumber.Calculate(A+B); Console.WriteLine(A + B = {0} sum); sum = CustomNumber.Calculate(F+G); Console.WriteLine(F + G = {0} sum); Console.ReadKey(); } } The output is: A + B = C F + G = AC
