## To build:
|
||||
|
||||
``` <!---sh-->
|
||||
make all
|
||||
```
|
||||
|
||||
|
||||
## To use:
|
||||
|
||||
``` <!---sh-->
|
||||
clear; ./prog
|
||||
```
|
||||
|
||||
|
||||
## Try:
|
||||
|
||||
``` <!---sh-->
|
||||
./try.sh
|
||||
```
|
||||
|
||||
|
||||
## Alternate code:
|
||||
|
||||
The original submitted entry was flickering when executed. This alternate
|
||||
code implements the original level of flickering.
|
||||
|
||||
The original submitted entry was flickering when executed. We added code to stop that.
|
||||
After adding this to the compile line:
|
||||
|
||||
```
|
||||
-DQ='fputs("\033[H",stdout);'
|
||||
```
|
||||
|
||||
We changed the source as follows:
|
||||
|
||||
``` <!---sh-->
|
||||
make diff_alt_prog
|
||||
```
|
||||
|
||||
|
||||
### Alternate build:
|
||||
|
||||
``` <!---sh-->
|
||||
make alt
|
||||
```
|
||||
|
||||
|
||||
### Alternate use:
|
||||
|
||||
``` <!---sh-->
|
||||
./prog.alt
|
||||
```

||||

## Judges' remarks:
|
||||
|
||||
This prize in **cyclonic coding** will certainly twist your perspective on C code.
|
||||
|
||||
This is not your garden variety tempest in a teapot. It's a tornado in a window!
