是否有可能NULL终止二维C ++结构数组？

Question

下午好，是否有可能NULL终止二维C ++结构数组？ 谢谢。

sPRIORITYANALYZER sArrayOfArrayAnalyzerArray[3][3] = {
{ 
  {mdMUReadWrite::First,mdProfiler::DataTypeFirstName},
  {mdMUReadWrite::FullName,mdProfiler::DataTypeFullName},
  {mdMUReadWrite::InverseName,mdProfiler::DataTypeInverseName} 
},

{ 
  {mdMUReadWrite::Last,mdProfiler::DataTypeFirstName},
  {mdMUReadWrite::FullName,mdProfiler::DataTypeFullName},
  {mdMUReadWrite::InverseName,mdProfiler::DataTypeInverseName} 
},

{
  {mdMUReadWrite::Zip9,mdProfiler::DataTypeZipOrPostalCode},
  {mdMUReadWrite::Zip5,mdProfiler::DataTypeZipOrPostalCode},
  {mdMUReadWrite::CityStZip,mdProfiler::DataTypeCityStateZip}

}
};

Answer 1

只有拥有指针数组时，空终止才有意义。 你必须在那里放一个完整的空行：

{ { 0, 0 }, { 0, 0 }, { 0, 0 } }

幸运的是，C和C ++让你只需要一次初始化，所以只有{ { 0 } }才能正常工作。 你需要使你的数组​​大小为[4][3] 。

晚上好，以下代码是正确的建议答案，并在Microsoft Visual Studio 9.0 C ++编译器上编译。 谢谢。

sPRIORITYANALYZER sArrayOfArrayAnalyzerArray [] [4] = {

{ 
  {mdMUReadWrite::First,mdProfiler::DataTypeFirstName},
  {mdMUReadWrite::FullName,mdProfiler::DataTypeFullName},
  {mdMUReadWrite::InverseName,mdProfiler::DataTypeInverseName},
  (mdMUReadWrite::MatchcodeMapping)0
},

{ 
  {mdMUReadWrite::Last,mdProfiler::DataTypeFirstName},
  {mdMUReadWrite::FullName,mdProfiler::DataTypeFullName},
  {mdMUReadWrite::InverseName,mdProfiler::DataTypeInverseName},
  (mdMUReadWrite::MatchcodeMapping)0
},

{
  {mdMUReadWrite::Zip9,mdProfiler::DataTypeZipOrPostalCode},
  {mdMUReadWrite::Zip5,mdProfiler::DataTypeZipOrPostalCode},
  {mdMUReadWrite::CityStZip,mdProfiler::DataTypeCityStateZip},
  (mdMUReadWrite::MatchcodeMapping)0

},

{ { (mdMUReadWrite::MatchcodeMapping)0, (mdProfiler::ProfilerDataType)0 }, { (mdMUReadWrite::MatchcodeMapping)0, (mdProfiler::ProfilerDataType)0 }, {(mdMUReadWrite::MatchcodeMapping) 0, (mdProfiler::ProfilerDataType)0 } }

};
