Hi,
I have googled but found nothing about this.
I am trying to generate a random number from a given array. But how do i do it?
Suppose:
I have an array int arr[]={3,89,99,4,55};
and i want to generate a random number among these numbers.
thanks in advance.
Jump to PostAll you need to do is use rand to get a random number in the range of your array and then use that number for the index of your array. Something like this:
cout << arr[(rand() % sizeOfArray)];
