[Doc] Fix: Misleading comment regarding storage struct reference in 06_ArrayAndStruct

[zhouCode]

Details(细节)

Description

In the initStudent1() function example, the comment says // assign a copy of student. However, in Solidity, assigning a state variable to a local variable with the storage data location creates a reference (or pointer), not a copy.

Using the word "copy" might confuse beginners into thinking it acts like a memory assignment.

Location

• File: 06_ArrayAndStruct/readme.md
• (Please also check the corresponding .sol source file if the code is duplicated there).

Current Code

function initStudent1() external{
    Student storage _student = student; // assign a copy of student
    _student.id = 11;
    _student.score = 100;
}

Suggested Fix

Update the comment to accurately reflect that a reference is being created:

function initStudent1() external{
    Student storage _student = student; // creates a storage reference to student
    _student.id = 11;
    _student.score = 100;
}
