The C++ language contains so many features that covering every one in a single book — especially a book intended for beginning programmers — is impossible. Fortunately, you don’t need to master all the features of the language in order to write big, real-world programs.

Nevertheless, you may want to look ahead at some of the features that didn’t make the cut for this beginner’s book, just in case you see them in other people’s programs.

The goto Command

This command goes all the way back to C, the progenitor of C++. In principle, using this command is easy. You can place goto label; anywhere you want. When C++ comes across this command, control passes immediately to the label, as demonstrated in this code snippet:
