Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The res directory is the directory used to store application resources."

A block of code is set as follows:

for i = 1 to Nr-1 stepsize 1 do
  SubBytes(state);
  ShiftRows(state);
  MixColumns(state);
  AddRoundKey(state,round_key[i]);
end for

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

adb shell pm path com.facebook.lite

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "After opening the software, click on Open File."
