can someone pls explain the function of {0} why can't i use +x to display the results of code instead

Answer 1

Like this?
Console.WriteLine("You entered " + x + ".");
//as compared to
Console.WriteLine("You entered {0}.", x);

It can be a matter of preference, but if you're putting out a lot of variables in one statement, using placeholders can look neater.

Answer 2

1. it is like what Tamra stated.

2. You can do that. Although SoloLearn courses/lessons normally do the {0} method, it still works if you just do the "+" method.

Answer 3

It depends on what you are doing what technique you should use, there are performance implications (usually minor) for each way of concatenating strings.

Additionally in C# 6.0 there is a friendlier way to use string format
string s = String.Format("{0}", x);
Is the same as this:
string s = quot;{x}";
