The difference between C and C + + struct

A struct is defined in C, and the typedef is usually used to alias the struct, for example:

1 struct Tagobject 2 {3     int weight; 4     int Price ; 5     int status; 6 }object;

Thus, when a variable is created with this custom data structure, it can be written like this:

1 OBJECT    objs;

And if it is not redefined with TypeDef, that is, by the original definition of the struct:

1  struct Tagobject 2 {3      int weight; 4      int Price ; 5      int status; 6 }object;

Thus, if you want to create a variable of this type, you need to define this:

1 struct tagobject    objs;

The essential reason is that the data type created is a struct tagobject, not a tagobject.

However, in C + + there is no need to define a TypeDef, struct and class The only difference is the default access level , which class is private and struct public .
