WebMar 17, 2024 · This is not universally true, but often true. It is not really useful to extend an int to 64 bits. It wastes space. If required, one can be 64 bits long and still have int be 32 bits. Otherwise, leave only long long for those cases where 64-bit integers are required. Most current implementations do the previous 64 bits long. set mp4 as background windows 10
