The difference between struct and class in C + +

In C + +, you can either use the struct keyword to define a class, or you can use the Class keyword to define classes, so what is the difference between the two?

The only difference is that the default access permissions for struct and class are different.

If we use struct keyword, The member that is defined before the first access specifier is public ; Conversely, if you are using class keyword, these members are private .

I think it is possible to understand that thestruct keyword is a c-style type definition,class is a C + + style type definition, and we know that object-oriented C + + has better encapsulation characteristics, so its members are defined by default as private .
