How to generate a random number in a range (10...20) using Swift [duplicate]
(1 answer)
Closed 6 years ago.
Need to set a random number between say 3 and 7. Everything I find is for Swift 2 and no longer works in Swift 3.
Thanks
This should work for my purposes.
var tapsNeeded = arc4random_uniform(4) + 3;

I have a new python learner, I want to ask a question about string format.
a = 3
len = 5
I want to format a as a binary number and the number length is 5. So I want to format it to '00011'.
How can I do in python?
answer = format(a,'b').zfill(len)

Generating a random integer from a range
(14 answers)
Closed 9 years ago.
I'm having a problem with my code, in which I try to generate a number between 0 and a dim user-defined variable. The line I'm having problem is:
arrayPos = rand()%dim;
I already called srand(time(NULL)) and the arrayPos is getting some wierd numbers like 9.267e-315 and so on.
Any ideas on how to fix it?
Thank you
The problem really was garbage memory, I restarted the computer and it worked like a charm

Generating random integer from a range
I am just starting to learn c++, and for a class assignment i'm supposed to use rand() and get a random number between 2 and 14. I know to get like between 1 and 10 i would do rand()%10+1
In my case would I need to do rand()%14+2?
I understand that others have posted similar questions, but they appear to all do between even multiples, such as 1 and 10, or 10 and 20 etc.
rand()%12+2
notice there is a gap of 12 number in between and your lower bound is 2.
