The type of the result is that of the promoted left operand. The behavior is undefined if the right operand is negative, or greater than or equal to the length in bits of the promoted left operand. 2 The value of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are zero-...
Long int = int = 32bit short int = 16bit 在16位系统中 short int = int = 16bit long int = 32bit 总之: short int = 16bit long int = 32bit 解决可移植性
6. dict==> 字典, 保存键值对, ⼀一样可以保存⼤大量量数据 7. set==> 集合, 保存⼤大量量数据. 不可以重复. 其实就是不保存value的dict 二.整数(int) 在python3中所有的整数都是int类型. 但在python2中如果数据量量比较⼤大. 会使⽤用long类型. 在python3中不存在long类型 bit_length()...
define clear(A,n) (A[(n)/(sizeof(unsigned long)*8)] &= (~(1<<((n)%(sizeof(unsigned long)*8)))A是数组，n是第几位，从0开始算
Mysql对BLOB和TEXT列进行排序和其他数据类型不同:它只对每个列前max_sort_length字节而不是整个字符串排序。如果只需要排序前面的一小部分字符,则可以减少max_sort_length的值,或者使用ORDER BY SUBSTRING(column,length)。 Mysql不能讲BLOB和TEXT列全部长度的字符串进行索引,也不能使用这些索引消除排序。

因此，在大多数现代C实现中，putchar(x)会将x的低字节写入标准输出。然后x >>= CHAR_BIT;将x中的...
