解决方案

好吧，它们将不可访问.您已将它们声明为私有，这意味着您已经明确说过:此类之外的任何人都不能访问这些".

更改对公众的访问权限，然后您可以访问它们...


顺便说一句:缩进你该死的代码！它使您阅读，我们阅读以及每个人都更容易理解.我打算通过添加一个代码块(它保留格式)来改善您的问题，但是由于您没有费心去缩进，所以我没有.帮助我们，为您提供帮助！

您应该将public设为类的公共接口"(即方法).

In this program i have error in bank :: initial_value is not accessible,
bank::deposit is not accessible,bank::displayis not accessible

解决方案

Well no, they won''t be accessible. You have declared them as private, which means you have specifically said: "No one outside this class can access these".

Change the access to public, and then you can access them...


BTW: Indent your damn code! It makes it easier for you to read, us to read, and everybody to understand. I was going to improve your question by adding a code block (it preserves formatting) but since you hadn''t bothered to indent, I didn''t. Help us, to help you!

You should make public the ''public interface'' (i.e. the methods) of your class.
