c++ - Can multiple threads access a vector at different places?

Question

Lets say I have a vector of int which I've prefilled with 100 elements with a value of 0.

Then I create 2 threads and tell the first thread to fill elements 0 to 49 with numbers, then tell thread 2 to fill elements 50 to 99 with numbers. Can this be done? Otherwise, what's the best way of achieving this?

Thanks

Yes, this should be fine. As long as you can guarantee that different threads won't modify the same memory location, there's no problem.
