shell script that emulates a simple number guessing game

ImSorry · #1 (**permalink**) 03-13-09, 10:36

Hello everyone,

I need your help. Im not familiar with Unix Shell Script. Help me to create shell script that emulates a simple number guessing game.

1) Preset an integer from the range of 1 to 100 in your script for the user to guess.
2) Start the game by asking the user to enter his/her name and, the script will display a welcoming message to the user followed by his/her given name. 3) Next, prompt the user to guess the number by entering an integer from the range of 1 to 100.
4) Allow the user to guess until he/she got the correct guess, and display a
congratulatory message.
5) Provide a hint for the user each time he/she entered a guess by displaying whether the user should guess lower or higher than 25, 50 or 75.

Any help will be appreciated. Thanks

is this for work or do you just want us to do your homework?

Looks more like HOMEWORK to me.
What have you tried so far?

Perhaps he works for the U.S. Department of Commerce Bureau of Economic Analysis, and has been tasked with developing a more accurate method of creating financial forecasts?

What you really need is a Requirements Guessing script. If you make a successful one of those, you will be a millionaire....for what that's worth, these days.

I think the following works:

Code:

#!/bin/sh
n=0
while [ $n -lt 123 ]; do
nzdf=`ps | sum | cut -c4-5`
n=`expr $n + 1`
wrd=To
done
n=`echo mbk nzdf -sol101 | sed 's/.*/0/'`
while [ `expr $n  + 4` -ne `expr $nzdf  + 4` ]; do
echo -n "Your guess:" | tr 'a-z' 'A-Z'
read n
if test `expr $n  + 4` -gt `expr $nzdf  + 4`
then
echo "$wrd big" | tr 'a-z' 'A-Z'
fi
if test `expr $n  + 4` -lt `expr $nzdf  + 4`
then
echo "$wrd small" | tr 'a-z' 'A-Z'
fi
done
echo "Correct" | tr 'a-z' 'A-Z'
exit -4

I should point out this uses an NZDF approach to design but I think this is exactly what's required for this particular OP.

Dear ImSorry

Did this get a good mark and did the lecturer have any follow up questions?
I'm just curious

That works very well. How could I change that so that it uses The RANDOM function to genrate a larger range of numbers, and only lets the user have 16 tries?

Also, if your really feeling nice how would I write a function called "checknum" that checks the number as opposed to the way it is currently written? and incorporate it into the code.

If you respond to this...thank you!!
