C language_ Structure pointer to access structure array

Structure pointer to access structure array

01—— Subscript traversal array

Previously, we used the subscript method to access this structure array , In fact, you can also use pointers to traverse the structure array .

02—— Pointer traversal array

A structure pointer variable is defined to store the first address of the array

We know that the array name is the first address of the array

for example ：

When the program needs to repeatedly call the pointer to traverse the array loop , Will it output normally this time ？

You can see that it will not output normally , as a result of ： When the program needs to repeatedly call the pointer to traverse the array loop, an error will occur , Will cause the array to go out of bounds ！！！

If you want to call more than once , Before each call, point the pointer variable to the first address of the array ：

That way there won't be any mistakes .
