1、所有比int型小的数据类型(包括char,signed char,unsigned char,short,signed short,unsigned short)转换为int型。如果转换后的数据会超出int型所能表示的范围的话,则转换为unsigned int型; 2、bool型转化为int型时,false转化为0,true转换为1;反过来所有的整数类型转化为bool时,0转化为false,其它非零值都转为tr...
Hence, the 16-bit unsigned integer has the range 0−65535 (216 − 1) and the 32 bit 0−4294967295 (232 − 1). There is also a 1-bit type for bit storage. Table 2.2. Range of Integer Variables NameTypeMinimumMaximumRange int1 1 bit 0 1 1 = 20 unsigned int8 8 bits 0 ...

rand()的范围很小,是16位的无符号整数,所以再乘以1000不会超出unsigned int的范围 这句话的意图应该是要生成15550 ~ 16550之间的数 这样写个近似的就好理解了unsigned aa=(unsigned)(((float)rand()/RAND_MAX)*1000)+15550 由于rand()返回的是整数,直接这么写rand()/RAND_MAX只能得到0,所以要...
例如,在C语言中,可以声明一个无符号整型变量为unsigned int或unsigned。请注意,在使用无符号整数时,要特别小心整数溢出的问题,因为无符号整数在达到其最大值后,如果再增加1,会回滚到0,而不是变成负数Unsigned Integer is a term used in computer science to refer to integers that can only be non-...
