Why it is necessary to put "+"after x and before y to display correct output. Via writeLine method ?

int x = 3; int y = x--; Console.WriteLine(x+" "+y);

Because you're adding the values together to create the output string. An alternative would be Console.WriteLine("{0} {1}", x, y);. In this case you use the formatting of strings to generate the output. (Also found under string.Format(...);)

In the above expression +" " concatinate the space between x and y.
