Random number generator from an array of number

Question

I had really like to generate random number from an array of numbers or character instead of using the time(0). I don't know if that can be possible with C++? If not is it possible in Python or which other programming language

Answer 1

Oh jajaja my english is not well yet. I didn't understand the "instead" word.
I don't know much about c++, but in python you can have any list (array) and use choice, below is an example:

from random import choice
myList = [1, 5, 2, 7, "hello", True, 9]
r = choice(myList)

In that code, the variable r can be any element of the list, the choice is random :)

Answer 2

Altering Sebastián's code:

int a[5] = {1,2,3,4,5};
cout << a[time(0)%5];

Answer 3

thanks so much this is exactly I expected

Answer 4

@hatsy Rei that's exactly what I wanted. thanks to Sebastian and your efforts in altering the code there by vanishing it to the right result

Answer 5

Here is an example

Basically with % you divide the number by the n = length of the array and the remainder can be between 0 and n, then you pass that number like the index of the array.
That's the best way using time.
In python you can import random and use random.choice(list) where list is... A list :D

Answer 6

thanks Sebastian but the array has no use in the program and it doesn't work as am saying. maybe I will try that one for Python but how can I implement it in Python

Answer 7

Jajaja you're right, sorry
Thanks :)
