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: " We called std::srand() and set a new seed, but each time we run the program, we're setting the same seed again "

A block of code is set as follows:

Stirng myStringLiteral = "hello";
string myString = { 'h', 'e', 'l', 'l', 'o', '\0' };

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

// If the enemy is dead remove it.
if (enemy.IsDead())
{
    enemyIterator = m_enemies.erase(enemyIterator);

    // If we have an active goal decrement killGoal.
    if (m_activeGoal)
    {
        --m_killGoal;
    }
}

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: " In Code::Blocks, add the following to the project's Build Options and Search Directories tab."
