关于arm9平台(32位) long long 类型,输出错误问题
arm9平台上，gcc4.2编译器下，如下代码：unsigned long longgetLongLongNum(void)
{
printf("sizeof(long long) = %d \r\n",sizeof(long long));
unsigned long long_num= 0x18011112222;
printf("_num = 0x%llx \r\n",_num);
return _num;
}
int main()
{
unsigned long longaaa = getLongLongNum();
printf("aaa= 0x%llx \r\n",aaa );
printf("bbb = 0x%llx \r\n",getLongLongNum());
}
结果如下：
sizeof(long long) = 8
_num = 0x18011112222
aaa = 0x11112222
sizeof(long long) = 8
_num = 0x18011112222
bbb = 0x1111222200000000
这是什么逻辑？
printf不支持吧。
