Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, folder names, filenames, file extensions, pathnames, and user input. Here is an example: “The class contains three properties, namely Id, Name, and Role, as well as two constructors.”

A block of code is set as follows:

int[,] numbers = new int[,]
{
    { 9, 5, -9 },
    { -11, 4, 0 },
    { 6, 115, 3 },
    { -12, -9, 71 },
    { 1, -6, -1 }
};

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

enum CurrencyEnum { Pln, Usd, Eur };

Any command-line input or output is written as follows:

Name     Birth date   Temp. [C] -> Result
Marcin   09.11.1988        36.6 -> Normal
Adam     05.04.1995        39.1 -> High
Martyna  24.07.2003        35.9 -> Low

Bold: Indicates a new term, an important word, an important sentence, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “It sounds complicated, but fortunately, it is very simple. A jagged array could be understood as a single-dimensional array, where each element is another array.”
