trying to make maths program

Yup, let's hint.

First you need to generate a random number. Whitetiger's formula is somewhat unaccurate, it should be INT(RND*(high-low+1))+low, but let's explain:

a) RND returns a random number each time it is used. The random number is in the range from 0 to 1 with decimals (this is, 0.324334, 0.88888, 0.67346 etcetera). If you want it (for example) to be from 0 to 10 you have to multiply by 10. The INT bit makes the number a integer, eliminating the decimals:

For example:

Code:

RND = .4828411
10 * RND = 4.828411
INT(10*RND) = 4

b) just multiplying RND for a number and then applying INT will only give you random numbers between 0 and the number you multiplied minus one. (I.E. INT(10*RND) will return numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 in random order). If you wanna, for example, have random numbers between 7 and 21, for example, you have to do some calculations:

b1) First you have to figure out how many different numbers there are. From 7 to 21 you have 21-7+1=15 different numbers (count with your fingers and you'll find out ). That's the number you have to multiply RND by.

b2) INT(15*RND) will give numbers from 0 to 15, just add 7: INT(15*RND)+7 and you'll get numbers from 7 to 21. Just some maths.

Now you should be able to figure out the formula: redo the steps I've posted and you'll find it:

Code:

randomNumber% = INT ( (high%-low%+1) * RND ) + low%

To make what you want, you have to generate two random numbers, then add them and do your loop until the user enters the number you calculated.

Here is a schematic pseudocode. Try to understand how it works and then translate it to QB and post here:

Code:

// PSEUDOCODE
s1 = RANDOM NUMBER BETWEEN 1 AND 10
s2 = RANDOM NUMBER BETWEEN 1 AND 10
sum = s1 + s2
BEGIN LOOP
   ASK USER FOR INPUT
LOOP WHILE USER'S INPUT <> sum

Good luck!

i tried it it dont seem to work it just says 3 guesses left, it is suppose to be a maths program, and that doesent seem to give me a sum,i need the computer to generate sum and then loop the sum until the answer is wright, and then generate aanother some.

It is frustrating when you spend 10 minutes writing a post... for nothing

[Agamemnus]

That's "right".

PLEASE proofread/spell-check/add grammar to your post.

im really sorry i didnt see all of your post thank you for your help , mate :oops:

eh, no problem

[KiZ]

I think he was possibly meaning thanks to Nath. :wink:

[whitetiger0990]

i wasn't talkin to him about that =P ((Rereads own post and gets confused))

[relsoft]

And you want all sums??? :roll: Relsoft style...

LOL.

[doughnut]

for the bit that says random number would i put in
Code:
RND = .4828411
10 * RND = 4.828411
INT(10*RND) = 4

and i need some help on getting it to print the sum and the users input, any help?

thanks
