C# Placeholder

When you define a seri in C#, it follows the variables in the list provided. The seri is defined inside the Console.Writeline ("{1}-{0}",word2,word1).

string word1 = "C#";

string word2 = "Programming";

Console.WriteLine("{0}-{1}",word2,word1);

// Output

// word2 is the first member of the seri

// word1 is the second member of the seri

// there is "-" sign between word2 and word1

// the result is Programming-C#

If you write Console.Writeline ("{0}-{1}",word2,word1); the result will be "C#-Programming"

Another example

int a = 5;

int b = 12;

int c = -7;

Console.Write("{2} {0} {1}", c, a, b);

// Output 12 -7 5
