How to detect unsigned integer overflow in C++?
Hello everyone! I'm a beginner C++ developer and I've encountered a problem with unsigned integer overflow. I'm writing a program for processing data from sensors, where values can be large. I'm using `unsigned int` to store counters, but I noticed that sometimes the program behaves strangely.
Here's an example code that confuses me:
```cpp
#include
int main() {

return 0;
}
```
I know that in C++, signed integer overflow is undefined behavior (UB). But what about unsigned? The standard says that unsigned overflow "wraps
