Access specifiers in c++ programming

in this post, you will learn about the access specifiers in c++ programming and learn how and why we use the access specifiers in c++ programming.

Access specifiers:

To use different types of access control we used access specifiers. specifiers set the visibility of class members. 

Types of access specifiers in c++:

There are three types of access specifiers in c++ for a class.

  • Private
  • Protected
  • Public

syntax:
           <name-of-access-specifiers>:

Note: we can only use access specifiers in a class.
Note: always use [:] colon sign at the end of access specifiers.

Example:
              public:
              private:
              protected:

private: 

all the data in private specifiers access inside the class.

Example: 
               class student
               {
                  private:

                       int a;
                       char c;

               };

protected:

we can only use protected data from base class to driven class.
you will fully understand the protected data when we learn about inheritance. 

Example:
                class student 
                {
                    protected:

                    int a;
                    char;
                };

public:

we can access all the public data from outside or inside the class. 

Example:
                class student
                {
                       public:

                       int a;
                       char c;
                };

Note: always use the [;] semicolon at the end of the class.
