1).计算机最小的存储单位是“位” 也就是bit或binary digits,用来存放一个二进制数,即 0或1。 8个二进制位为一个字节Byte。 2).对于 16-bit(16位)的计算机,int是以两个字节来储存的,而32-bit的计算机,则是以4个字节,即32个bit来储存的。 如果想要明白singed与unsigned的区别,除了这两个基本知识,还需要...

二十四节气起源于黄河流域，也反映了典型北方气候特点。远在春秋时期，中国就已经能用土圭（在平面上竖一根杆子）来测量正午太阳影子的长短，以确定冬至、夏至、春分、秋分四个节气。一年中，土圭在正午时分影子最短的一天为夏至，最长的一天为冬至，影子长度适中的为春分或秋分。春秋时期的著作《尚书》中就已经对节气...

在C语言中,unsigned int是一种无符号整数类型,它可以存储从0到4294967295的整数值。unsigned int数组是一个包含多个无符号整数的数组,而位移操作是一种在位级别上操作整数的方法。 位移操作有两种:左移(left shift)和右移(right shift)。左移操作将整数的二进制表示向左移动指定的位数,右移操作将整数的二进制表示...

because Microsoft definesDWORDin<windows.h>rather than being a type in C++. Microsoft has defined its word size to be 16 bits long, and theDWORDis defined as 32 bits long across all platforms. The most significant bit (MSB) ofDWORDis not allocated for signing because it is an unsigned ...
