Maybe some possible questions in your Cpp-Primer/ch02 about cppprimer HOT 7 CLOSED

Hi, @cxs944745612 Good to see you. 😄

1 and 2, you are right, and I have tried to fix it.

3 int *const p2 = &i2, we can judge the variable type according by it's name. Or, the question make no sense. Thus, i2 should be an integer, rather than double as you say.

4 I can't sure whether it will appear this error message. I am try to list the related codes as following:

const int v2 = 0;
int v1 = v2;
int &r1 = v1;
// above is previous exercise (Exercise 2.30)
r1 = v2;

Use Clang 3.5 and gcc 4.9.2, All passed. Could you please tell me what environment do you have?

Thx a lot for bug reporting. 👍

I'm very sorry ,it's my fault .You're right!
what's more,you say"we can judge the variable type according by it's name",it means that we keep i2 as a default integer variable .( i: integer, d: double, f: float. so d2 is a double variable in c++ primer ? like this？)
My English level is very poor , so can you understand what I want to express? I really want to say Chinese ! thanks a lot for your guidance！

我觉着你们俩可以用中文讨论来着：）

那咱们以后就用中文吧～ 🇨🇳

i: integer, d: double, f: float. so d2 is a double variable in c++ primer ? like this？

是的，就是这样，这本书的命名很讲究，也为初学者培养好不乱命名的好习惯。除了你提到的，第二章里，还有 r 代表 reference, c 代表 const, p 代表 pointer.
