推荐答案

转换二进制文件一个数字的表示（就像一个字符串，例如00101100）到它的八进制表示非常简单，只是从右边开始，转换 3 字符组，例如

Converting the binary representation of a number (that is a string like, for instance "00101100") to its octal representation is pretty simple, just convert group of 3 characters at time, starting from the right, e.g.

00101100 -> 00 101 100 -> 054

另一方面，如果你只需要一个数字的八进制表示，它甚至更简单，例如

On the other hand, if you just need the octal representation of a number than, it is even simpler, e.g.

int x = 44;
cout << oct << x << endl;
