Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
The object is to enter a number, then have another classmate guess the entered number.


2. Relevant commands, code, scripts, algorithms:
I am trying to use an if-then-else statement to accomplish my goal


3. The attempts at a solution (include all code and scripts):
#! /bin/csh
echo "Please select a number to be guessed"
read num1
1:
echo "Please guess a number"
read num2
if (num2 == num1) then


echo "Congratulations!! You have guessed correctly!"
else
echo "Sorry, but that number is incorrect."
goto 1
endif



4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

<Hoping I did the template correctly>

The problem I am encountering is that no matter what number I enter, it always echos "Sorry, but that number is incorrect" even if I enter, say 11, for both num1 and num2. And yes, I am a complete coding noob. xD

In my cshell there is no read build-in.

As I remember, the way to read is:

Code:

set num1 = $<

In any case when you access the values of num1 and num2, they are variables, and should be referenced as $num1 and $num2

i.e.

Code:

if ( $num2 == $num1 )

I'm struggling to understand why anyone would teach c-shell... it really is dreadful.

Thanks for the reply scottn,

I think I understand what you said so I changed my coding to the following:

#! /bin/csh
echo "Please select a number to be guessed"
set num1 = $<
1:
echo "Please guess a number"
set num2 = $<
if ( $num2 == $num1 ) then


echo "Congratulations!! You have guessed correctly!"
else
echo "Sorry, but that number is incorrect."
goto 1
endif


---After executing it lets me enter the first two numbers and then it returns the error "Event not found"

I found this in the Wikipedia article on the shell:

I'd read this:

Escape exclamation marks!!!

Code:

echo "Congratulations\!\! You have guessed correctly\!"

Wonderful..heh

What shell would you recommend doing this in? I dont think there are any requirements as to what shell to use. Are there any that might be better suited for my needs?

P.s. I appreciate the help

See what forum members think:

(and I should add, before someone reminds me, it's really bad practice to use goto's!)

haha i was about to say the exact same thing. it's been ages since i last saw a goto statement
