WebJun 25, 2024 · If you mean to clear all bits in first operand witch are sets in other one, you need to make a binnary and with negated second operand: std::bitset<10> first … WebFirst the result with VC++: Time using assign: 0.141 Time using loop: 0.068 Time using clear: 0.141 Time using fill: 0.087 Ignore: 16777216 16777216 16777216 16777216 So, with VC++, the fastest method is what you'd probably initially think of as the most naive -- a loop that assigns to each individual item.

Web【笔记】C库函数——bitset 看到有大佬掏出这个库函数，一愣。这绝对是未曾想象过的道路，长见识。有时候做题总能碰见稀奇古怪的库函数，每个都令我大开眼界。以后看到感兴趣的都会记录一下，感觉是个好东西，算是学习道路… WebUsing scoped enums for bit flags in C++. An enum X : int (C#) or enum class X : int (C++11) is a type that has a hidden inner field of int that can hold any value. In addition, a number of predefined constants of X are defined on the enum. It is possible to cast the enum to its integer value and vice versa. This is all true in both C# and C++11. WebC++11 Set bits Sets bits: (1) all bits Sets (to one) all bits in the bitset. (2) single bit Sets val as the value for the bit at position pos. Parameters pos Order position of the bit whose value is modified. Order positions are counted from the rightmost bit, which is order position 0. photographe mariage clamart
