For printf() we can use this format `"%.*s", cast(int)s

says that this specifier is invalid.
The * has a different meaning for scanf than for printf ([1] vs
[2]).
There's also the issue that a string is immutable(char)[].
If you really, really, really, must use scanf:
```
char[bufSize] buf;
scanf("%s", buf.ptr);
```
But please don't. This is D, not 1990s C.

Thanks! Actually for some reason. It won't accept a char[size]. I
created a heap allocated (with pureFree and pureMalloc) chrar*,
then used fgets() and created an empty string and looped through
the result adding one by one character until the '\n' which is
not included.
