C language shu zu-CodePudding

Excuse me, the last element of an array of c language can't assignment

CodePudding user response:

You understand the last element of which is to point to?
Array a [5], for example, the last element is a [4] no problem, can the assignment, but a [5] have a problem, an array, the array subscript is from 0 to 4 a total of five elements

refer to the original poster m0_46244162 response:

could you please tell me the last element of an array of c language can't assign it

It depends on your integer array you can literally assignment
For character array, you can also see it as a string, the string at the end there is a \ 0 represents the end of the
String or character array usually use Pointers to operate it operated by pointer string has a important conditions: according to whether it is at the end of \ 0 to judge whether a pointer to the string end
If you put the last element of an array of characters assignment that you use the string pointer manipulation is vulnerable to an array of topics because you don't know at the end of the string

Can literally assignment? How can an error said damaged stack

Bosses, this will have any exceptions such as an array of strings can not be an integer array can have this kind of situation??

Who do this will have any exceptions such as an array of strings can not but integer array can, for example, the said downstairs

CodePudding user response:

As long as it is within the array, can be assigned, suggest the original poster posted code, if there is an error, is likely to be caused by crossing the line, on the stack is not recommended to define large arrays

Without exception, the end of the string the last character is also of its own guarantee, you do not set, it's not over yet,
