Conventions used

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

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The input() method is used to get an input from the user."

A block of code is set as follows:

pragma solidity ^0.4.0;
contract TestStruct {
  struct Trade
  {
    uint tradeid;
    uint quantity;
    uint price;
    string trader;
  }
  //This struct can be initialized and used as below
  Trade tStruct = Trade({tradeid:123, quantity:1, price:1,
trader:"equinox"});
}

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

$ sudo apt-get install solc

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "If you need something different, click on the DOWNLOADS link in the header for all possible downloads:"
