C++ Source Code Formatting

Some languages, such as FORTRAN, are line-oriented, with one statement to a line. For these languages, the carriage return (generated by pressing the Enter key or the Return key) serves to separate statements. In C++, however, the semicolon marks the end of each statement. This leaves C++ free to treat the carriage return in the same way as a space or a tab. That is, in C++ you normally can use a space where you would use a carriage return and vice versa. This means you can spread a single statement over several lines or place several statements on one line. For example, you could reformat myfirst.cpp as follows:

#include <iostream>     intmain() {   using    namespace         std; cout            <<"Come up and C++ ...
