Example text

Another example is C-x 2 which means to press the Ctrl key together with x and then press only the key 2. This is a shortcut to the command that splits a window horizontally to two equal parts. The most useful shortcuts are M-x (press the Alt key siumutaneously with the x key) and C-g. The first command takes us to the minibuffer where we can give a command by typing its name. For example, type M-x and then type save-buffers-kill-emacs in the minibuffer (this will terminate Emacs). The second one is an “SOS button” that interrupts anything Emacs does and returns control to the working buffer.

Emacs files. You may also customize Emacs from the menu commands Options→Customize Emacs. 4. 4 35 The C++ Programming Language In this section, we give a very basic introduction to the C++ programming language. This is not a systematic exposition and you are expected to learn what is needed in this book by example. So, please, if you have not already done it, get in front of a computer and do what you read. You can find many good tutorials and books introducing C++ in a more complete way in the bibliography.

Omitting using namespace std does not make cout inaccessible. One can use its “full name” std::cout instead. Remove the statement and try it. cout is part of the C++ Standard Library. All elements of the library belong to the std namespace and their names can be prefixed by std:: Using the using namespace std statement, the prefix may be omitted. 4. THE C++ PROGRAMMING LANGUAGE 37 i n t main ( ) { cout << ” H e l l o World ! \ n” ; } i n t main ( ) { cout <<” H e l l o World ! \ n” ; } Finally notice that, for C++, uppercase and lowercase characters are different.
