c++ - 指向结构的指针的 C++ 数组

Answer 1

You're ... trying to assign a pointer to an int. You can't do that.

int *pointerArray[20];

would need to be

Node *pointerArray[20];

However, when you do this:

pointerArray[i]=&(*n);

you're doing this:

pointerArray[i] = n;

Is that what you mean to be doing? You say you want to use an "array of pointers to structures". You're passing a pointer to a pointer here, and trying to store that.

void insertNode(Node *n,int i)
{
    pointerArray[i] = n;
}

Would be storing Node pointers in an array.

Answer 2

You declared pointerarray as type int*[]. You want it to be type Node*[].
