Intentional Overflow

I'm wondering if it is allowed in C++ to use overflow on purpose. In specific I want to increase a counter every cycle and when uint32_max is reached start from 0.

In my mind the easy way would be:

uint32_t counter = 0;
while(condition)
{
    counter++;
    ...
}

or would you manually reset the counter?:

uint32_t counter = 0;
while(condition)
{
    if(counter == uint32_max)
    {
        counter = 0;
    }
    else
    {
        counter++;
    }
    ...
}

That is fine because you used uint32_t. Unsigned integers do not overflow but wrap-around from the maximum value to zero. Such behavior is well-defined in C++, unlike signed integer overflow/underflow.
