如何循环二进制数字的数字？

Question

我有一个二进制数1011011,我怎么能一个接一个地遍历所有这些二进制数字？

我知道如何使用modulo和division对十进制整数执行此操作.

Answer 1

int n = 0x5b; // 1011011

真的,你应该这样做,一般十六进制表示更好:

printf("%x", n); // this prints "5b"

要获得二进制文件(重点是易于理解),请尝试以下方法:

printf("%s", "0b"); // common prefix to denote that binary follows
bool leading = true; // we're processing leading zeroes
// starting with the most significant bit to the least
for (int i = sizeof(n) * CHAR_BIT - 1; i >= 0; --i) {
    int bit = (n >> i) & 1;
    leading |= bit; // if the bit is 1, we are no longer reading leading zeroes
    if (!leading)
        printf("%d", bit);
}
if (leading) // all zero, so just print 0
    printf("0");

// at this point, for n = 0x5b, we'll have printed 0b1011011
