            for (int i = 1; i < 10; i++)
            {
                for (int j = 1; j <= i; j++)
                {
                    c = i * j;
                    Console.Write("{0}*{1}={2}  ", i, j, c);
                }
                Console.WriteLine();
            }
            Console.ReadKey();

    }
}

Answer 2

class Program
{
static void Main(string[] args)

{
for(int i=1;i<10;i++){
String str = "";
for (int j=1;j<=i;j++) {
String tem = i + "*" + j + " = " + (i * j) + " ";
str = str + tem;
}
Console.WriteLine(str);
}
Console.ReadKey();
}
}
