## To build:
- make all
+```sh
+make all
+```
## To run:
- echo 4 | ./baruch
- echo 7 | ./baruch
+```sh
+echo 4 | ./baruch
+echo 7 | ./baruch
+```
+
+## Try:
+
+```sh
+echo 2 | ./baruch
+echo 3 | ./baruch
+```
+
+Why is there no output?
+
+### Alternate code:
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) provided alternate code
+for users using Turbo-C or MSC, based on the authors' comments below, except
+that he did not change the `" #Q"` string as that showed worse looking output
+instead of improved output though he has no way to test the compilers in
+question. YMMV. Thank you Cody (though we all think [no
+one](https://en.wiktionary.org/wiki/no_one#Pronoun) [very
+few](https://en.wikipedia.org/wiki/0)
+[users](https://en.wikipedia.org/wiki/Microsoft_Windows)
+[here](https://www.ioccc.org) will need it :-) )!
+
+To compile:
+
+```sh
+make alt
+```
+
+Use `baruch.alt` as you would `baruch`.

This program demonstrates the claim that in C, any program
can be written using a single 'for' statement, as long as it is
long enough..
