Q&A
| Q1: | If C++ offers better alternatives than the preprocessor, why is this option still available? |
| A1: | First, C++ is backward compatible with C, and all significant parts of C must be supported in C++. Second, there are some uses of the preprocessor that are still employed frequently in C++, such as inclusion guards. |
| Q2: | Why use macro functions when you can use a regular function? |
| A2: | Macro functions are expanded inline and are used as a substitute for repeatedly typing the same commands with minor variations. However, templates offer a better alternative. |
| Q3: | What is the alternative to using the preprocessor to print interim values during debugging? |
| A3: | The best alternative is to use watch statements within a debugger. For information on watch statements, consult your compiler or debugger documentation. |
