Totlas and Counters help

Post by Guest »

Hi, could someone help me understand how Totals and Counters work and give me example of some questions.


1) Generate 40 random integers between -50 and 50 and then display how many of those number were positve.

2) Simulate the tossing of a coin 20 times, display if it was heads or tails for each toss and then display how many heads were tossed and how many tails were tossed.

3)Write a program that asks for a password, do not let the user continue until the password is geussed correctly. At the end display how many tries it took to get the correct password.

Help would be really appreciated, thanks.

As soon as you've showed us how much of your homework assignment you've already done, I'm sure someone here would be willing to help you out. :D

Yes, exactly my feelings.
And by the way, since you're asking for code, not just a quick answer, why don't you register and become a member? It's nice to know who you're spending time and effort to help. This is a QBasic programming forum, not a question/answer radio program.

The above post was mine. (Moneo)

actually, it was the problem with the author if this thread...that was me thinking I was logged in.

anyway, for the unit we received about 10 worksheets with about 10 questions in each of them. In the beginning we started off with simple things like variables, and then we moved onto things like If statements and do loops. I was keeping up with most of it, up until we got to random numbers, I figured out how most of it works but I can't figure out how to choose from negative and positive random numbers (hence the reason why I couldn't do one of those questions) I understand most of it, the only trouble I have is with Totals, Counters, and some trouble with random numbers. If someone could show me how the three questions work I should be able to figure out how counters work and get the answer to my only question about random numbers.

This still looks guest wants us to do his homework...
Some hints:-

-1 < ? < 1

Figure out what the question mark is and you have the conditional for testing positive or negative...

How do you count?
You add a number to the number you already have...
1+1=2
?+1=3
?+1=4
change the ? to a letter and you have algebra
x+1=4
so x is what?
and what was it in the previous statement?
Turn the algebraic statement around and you have a basic assignment statement:-
?=?+1

The rest, as they say is up to you...

summing and counting

Post by Zim »

Ok, here's a couple of lines of code for you:

To count something you must start with a counter set to zero!

Code: Select all

sumpos=0
To test if something is positive check if it's greater than zero:

Code: Select all

if num>0 then.....
To count, add "1" to the counter (conditionally, of course):

Code: Select all

if num>0 then sumpos=sumpos+1
Play with that a little and see if you begin to understand.

Ok, so who are you anyway?

Here's some code to generate random numbers between -50 and 50. But bear in mind that zero will be one of these random numbers.

Code: Select all

defint a-z
RANDOMIZE TIMER

Lower = -50
Upper = 50
R = INT(RND * (Upper - lower + 1)) + lower
R is the random number between -50 and 50.
