**总结:**对于uint16_t,uint32_t,uint64_t的使用,在程序中加入typedef unsigned __int16 uint16_t;typedef unsigned __int32 uint32_t;typedef unsigned __int64 uint64_t; 输入语句:scanf("%I16u",&num); 输出语句:printf("%I64u",num);(u表示unsigned,有符号时使用d)...

int32_t val = -121; uint32_t new = (uint32_t)val; printf("val = 0x%x, %d, new = 0x%x, %d\n", val, val, new, new); 结果为: val = 0xffffff87, -121, new = 0xffffff87, 4294967175 负数在计算机是以补码形式存在的,-121的补码为0xFFFFFF87,如果解释为无符号数即为4294967175, ...
printf("指数:%8x\n",F2); printf("符号位:%8x\n",F3); return Hex_Data; } void main(void) { float a = 0; uint32_t b = 0; while(1) { printf("请输入一个浮点数\n"); scanf("%f",&a); b = Float_To_Hex(a); printf("Hex数据:%8x\n",b); ...
intans=100;intcows=10,fla=24 声明为变量创建和标记存储空间,并为其指定初始值。 1.3 int 类型常量 C语言中将不含小数点和指数的数作为整数。 1.4 打印int值 可以采用printf()函数打印int类型的值。%d指明了在一行中打印整数在位置,%d称为转换说明,它指定了prinf()应使用什么格式来显示一个值。
short int(简写为short):占用空间不多于int,一般占用2个字节(整数范围为-32768～32767)。 long int(简写为long):占用空间不少于int,至少为4个字节。 long long int(简写为long long):占用空间多于long,至少为8个字节。 默认情况下,short、long、long long都是带符号的(signed),即 signed 关键字省略了。它们也...
