是否定义了使用static_cast将const unsigned char&转换为const unsigned long long&? constexpr unsigned char arr[sizeof(unsigned long long)]{ 1 }; constexpr bool value = static_cast<const unsigned long long&>(arr[0]) == 1; 加入int main(){},这将在Coliru、Ideone和VS2015上编译而没有错误或警...
unsigned int val = reinterpret_cast<unsigned long>(p); return (unsigned short)(val ^ (val>>16)); } int main() { int a[20]; for(int i=0;i<20;i++) { cout<<Hash(a+i)<<endl; } return 0; } 运行结果如下: 这段代码适合体现哈希的思想,暂时不做深究,但至少看Hash函数里面的操作...
[severity:I’m unable to use this version] [regression] [worked-in:17.10.3] After upgrading, I got link errors with unresolved references to __ltof3 and ultof3 functions. It appears that the compiler implementation of static_cast from long and unsigned long to float c...
关于waveOutOpen() 的用法问题我在用MFC 编程,当我用到语句:waveOutOpen(&hWaveOut,WAVE_MAPPER,&waveFormatEx,(unsigned long)waveOutProc,0L,CALLBACK_FUNCTION) 编译后却得到: error C2440: 'type cast' : cannot convert from 'void (__stdcall CExchange::*)(struct HWAVEOUT__ *,unsigned int,unsigned...
