C++ random numbers!

[chmate]

Hello!

I've been trying to create an algorithm which picks a number randomly from array. P.S i have an array like A={1,4,-1,3,-7,2,-14} and I want to pick a number randomly from array.

Any idea?

Thank you.

Why don't you use rand() to draw index?

Hi borek, can you show me an example?

Thank you.

Hello!

I've solved my problem. I've been looking for this part of code:

srand(time(NULL));
random = arr[rand() % (sizeof(arr) / sizeof(arr[0]))];

Thank you.
