如何管理在C ++比特/二进制？ [英] How can I manage bits/binary in c++?

问题描述

我需要做的是开放与0和1的文本文件，找到文件中的列之间的模式。

What I need to do is open a text file with 0s and 1s to find patterns between the columns in the file.

所以，我首先想到的是每一列解析成的bool的一大阵，然后再做列之间的逻辑（今阵列）。直到我发现布尔变量的大小实际上是一个字节不是有点，所以我会浪费内存的1/8，每个值赋值给一个布尔值。

So my first thought was to parse each column into a big array of bools, and then do the logic between the columns (now in arrays). Until I found that the size of bools is actually a byte not a bit, so i would be wasting 1/8 of memory, assigning each value to a bool.

它甚至在为800x800值的网格相关的​​？什么是处理这个的最佳方式？
我想AP preciate的情况下，code片段它是一个复杂的答案

Is it even relevant in a grid of 800x800 values? What would be the best way to handle this? I would appreciate a code snippet in case its a complicated answer

推荐答案

您可以使用的std ::矢量＆lt;布尔＆GT; 这是采用了紧凑载体的特存储布尔.... 1位不是8位。

you can use std::vector<bool> which is a specialization of vector that uses a compact store for booleans....1 bit not 8 bits.
