Placeholders count from zero
Ans should be consecutive
Console.WriteLine({0} {1} {2}, a, b, c)
You are allowed to change the order, but not to skip a number
Console.WriteLine({0} {2} {1}, a, b, c)

Answer 2

If you don't like placeholders, the $ is an alternative.

Example:
string a = "bob";
string b = "tod";
string c = "blot";
Console.WriteLine(quot;{a} { b} { c}");
