String formatting

var name = "Laci";

var greeting = string.Format("Hello {0}!", name);
WriteLine(greeting);

var greeting2 = string.Format($"Hello {name}!"); // it's called string interpolation
WriteLine(greeting2);

Output:

Hello Laci!
Hello Laci!

Formatting a double to two decimal places

WriteLine("A két pont közti távolság: {0:0.00}", Distance(p1, p2)); // 5.83 , for instance

Where Distance() returns a double value.
