All you need to know about System.Console.Write function

• If you put the line using static System.Console; at the top of the file you can use simply Write instead of the full name System.Console.Write.

  Compared to Write the method WriteLine adds the newline symbol at the end of the output.

• We shall be mostly using formatted output where the first argument to Write is a (format) string that specifies how things must be written. If the format string is the only argument, this string is simply printed to the standard output (which by default is your terminal). For example,

  Write("hello\n");

  produces

  hello
  

  (the string \n represents the newline character).

• Besides the first argument — the format string — Write can have more arguments which then must be the names of the variables (or expressions) which you want to print out. In this case the format string must contain placeholders for the arguments to be printed. The string is then printed with placeholders replaced by the values of the given variables (expressions).

  By default the first argument after the format string takes the placeholder number zero "{0}", the second argument after the format string takes the placeholder number one "{1}", and so on.

  For example

  int n=123; Write("n = {0}, twice n = {1}, five times n = {2} \n", n, 2*n, 5*n);
  

  produces

  n = 123, twice n = 246, five times n = 615
  

  The same output can also be achieved using the dollar-sign (the string interpolation operator)

  int n=123; Write($"n = {n}, twice n = {2*n}, five times n = {5*n} \n");
