Bitset sizeof a *8 a
WebApr 28, 2015 · There is no guarantee that sizeof (bitset<8>) is 1. On my implementation, it happens to be 8. Thus, any assumption you are making about the internals of this class is just that - an assumption. If you want to convert an unsigned char to a bitset<8>, there is already an easy way to do that: unsigned char myChar = 0x0F; std::bitset<8> bs (myChar); WebNov 1, 2024 · I am using std::bitset to represent short DNA sequences (haplotypes). For my purposes, I need to be able to convert each such sequence into a single integer. At the moment, it seems like this requirement bounds my sequences to be of length <=64 because of the way std::bitset::to_ullong works?

WebNov 22, 2016 · BITSET_INIT is a preprocessor macro you can use to initialize an empty bitset. If you cannot or do not want to use it, you can use bitset_init () to initialize a bitset. The two are equivalent. bitset_free () releases the dynamic memory allocated for the bitset. After the call, the bit set is gone, and the variable used is re-initialized.

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. bamboosang dokumentenkamera software
