boolean operations instead of c-style tests?

In the file https://github.com/ntmoore/phys332_fall21/blob/main/11_4_vary_brightness.v

Lines 23, 26, 30 are written a C/Java style == logical tests.  Could we also write these as boolean operations?  eg 

```
if(ctr==8'b0000) begin  
```

What about something like
`if( ~ctr[3] & ~ctr[3] & ~ctr[3] & ~ctr[3] ) `
???
