struct的繼承

參考自：

When deriving a struct from a class/struct, default access-specifier for a base class/struct is public. And when deriving a class, default access specifier is private.

當struct繼承時，默認的access specifier是public；而class繼承時，默認的access specifier則是private。

在TensorRT/samples/common/argsParser.h中CaffeSampleParams對SampleParams的繼承：

struct SampleParams{
       int batchSize{
   1};                  //!< Number of inputs in a batch    int dlaCore{
   -1};                   //!< Specify the DLA core to run network on.    bool int8{
   false};                  //!< Allow runnning the network in Int8 mode.    bool fp16{
   false};                  //!< Allow running the network in FP16 mode.    std::vector
   
     dataDirs; //!< Directory paths where sample data files are stored    std::vector
    
      inputTensorNames;    std::vector
     
       outputTensorNames;};struct CaffeSampleParams : public SampleParams{
       std::string prototxtFileName; //!< Filename of prototxt design file of a network    std::string weightsFileName;  //!< Filename of trained weights file of a network    std::string meanFileName;     //!< Filename of mean file of a network};
