However, there are a few shortcomings of preprocessor macros that tip the scales in favor of inline functions in C++. These are: Macros can not access private class members: This inhibits their ability to encapsulate data and thereby compromises data privacy. Macros lack type checking: This can...

The CAMERA_BOOST_PCLK preprocessor define can be enabled in the compiler settings or directly in file stm32h747i_discovery_camera _ex.c. /* Set CAMERA_BOOST_PCLK=1 to operate the OV5640 camera in optimal mode. Note: when operating th...

In the derived class, the return type must be a pointer or reference to a type that is derived from the return type of the base class.ExampleOpen Compiler #include <iostream> using namespace std; class Vehicle { public: // Final method virtual void honk() final { cout << "Vehicle ...
Using preprocessor directives. Instead of using a regularifstatement, functions can use the#ifpreprocessor directive that selectively compiles a function after evaluating its branch conditions. This approach avoids code duplication but reduces the performance benefits of precompiled Metal shading language cod...
For this to work, you have to run a special preprocessor on your code before compiling. Performance is poor, but it works on compilers with very poor template support. [Libsigc++]. An event system based on Qt's. It avoids the Qt's special preprocessor, but requires that every target ...

What is the purpose of the preprocessor in the C program compilation process? 7. At what stage in the program compilation process are predefined library files implemented? 8. When would it be necessary to use the extern storage class specifier in an mbed C program? 9. Why is the #ifndef ...
