Just saw a program about the largest cosmological simulation ever, requiring 5 years, a 512 cpu supercomputer, a terabyte of RAM and producing 20 Tb of data. The head researcher described how they almost lost all the work due to an integer overflow, and then went on to explain how computers can’t count above 4 billion. Funny, my 1 cpu laptop with a mere thousandth of a terabyte of RAM can count to much more than 4 billion.

All of which tomfoolery just reinforces my opinion that, unless you’re writing an operating system, device driver, or similar then you have no business using C or C++.
