If you need I/O performance, you can almost always do better than `printf()`.
`gets()`, `scanf()` using `%s`, and `printf()` using `%s` are security hazards (vulnerable to buffer overflow and generally error-prone).
In C11, they are replaced by `gets_s()`, `scanf_s()`, and `printf_s()` as safer alternatives, but they are still not type safe.
C11 defines some "optional extensions" that do extra checking of their arguments.
If present in your C library, `gets_s()`, `scanf_s()`, and `printf_s()` may be safer alternatives, but they are still not type safe.
