algorithm : Two stacks are used to store numbers and operators, and one string is used to accept the expressions to be computed, use the symbols in the string to compare with the stack storing the symbols. If the priority of the external operators

In the previous article, we used Enum to simulate the number of compile times, but the constants in C ++ compilation are also of the type (C only has int and double. What? You do not know sizeof ('1') = sizeof (1)?) in C )?). Therefore, it is normal

Vector is a very useful container in C ++. It is defined in generics and can dynamically access any type, including built-in and composite types. vector is defined in the header file of . 1vector object initialization is generally based on the

The enumeration definition includes the keyword Enum, followed by an optional Enumeration type name and a pair of curly brackets, which contain enumeration members. 1 By default, the first enumerated member is assigned a value of 0, and the

When using an object that contains content, there are two main optional methods for objects that represent Class X: 1. A Member whose life type is X 2. A member whose life type is x * or X & If the pointer value never changes, these options are
