头部进一步定义了这些(和一些其他)类型的最小值和最大值的宏:例如,INT_FAST_8_MIN和INT_FAST_8_MAX代表std::int_fast8_t。不过,获得这些值的标准 C++ 方法是使用下面讨论的<limits>工具。 算术类型属性<limits> std::numeric_limits<T>模板类提供了大量的静态函数和常量来获取数字类型T的属性。它专门用于所...
In this tutorial, we explain difference between C and C++ languages. Both of these are programming languages and C++ is a superset of the C.
The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to.Pointer InitializationAfter declaring a pointer variable, you need to initialize it with the address of another variable using the address of (&) operator. This ...
