The sizeof knows nothing about "dynamic array" sizes. The sizeof is a compile-time value denoting the size of the type that's specified. The sizeof(foo) is more than likely going to be either 4 or 8, depending on the pointer size. Basically the code you wrote is fundamentally flawed in multiple areas. got sunshine in my pocket

WebSep 1, 2010 · 0. A bitset has a fixed number of bits. You specify bitset -- on most systems, CHAR_BIT is 8 so you will have an 8-bit bitset. When you try to stuff a bigger number into the bitset, the most significant bits are discarded. If you know in advance the largest numbers you will have to deal with, you can specify eg bitset<16> or bitset<32>.Webbitset requires size as a template parameter, meaning the size has to be capable of …
