The const keyword is required in both the declaration and the definition. A constant member function cannot modify any data members or call any member functions that aren't constant. Example 复制 // constant_me
A member function declared with the const qualifier can be called for constant and nonconstant objects. A nonconstant member function can only be called for a nonconstant object. Similarly, a member function declared with the volatile qualifier can be called for volatile and nonvolatile objects. ...
修饰一个成员函数和成员变量(Member function and Member varibale) 所以我们慢慢来说一说,这个关键字修饰的变量都会成为常量。 虽然没有被这个const关键字修饰的类成员或者变量和函数,能够访问被这个const关键字修饰的类成员或者变量和函数。 但是被这个const关键字修饰的类或者变量和函数,不能够访问没有被这个const关键...
You can call either constant or nonconstant member functions for a nonconstant object. You can also overload a member function using theconstkeyword; this allows a different version of the function to be called for constant and nonconstant objects. ...

If the function is supposed to be private, we can put it into priv/, so it is not a hard blocker. But probably a clearer error should be in place? It is also a problem for records that contain private functions.Activity lpil commented on May 28, 2023 lpil on May 28, 2023 Member...
In conclusion, using the constant value of PI in C++ is a fundamental skill that can greatly enhance your programming capabilities. Whether you choose to define PI as a constant variable, use the cmath library, or create a custom function, each method has its advantages. The choice ultimately...
