先看一段代码: int main(void) { int *pI = new int; int *pArray = new int[10]; int size = *(pArray-1); delete pI; delete [] pArray; // delete是如何知道pArray数组大小的? return 0; } 看反编译后代码,没能直接找到答案,于是在网上搜索发现这样一篇文章:<Mismatching scalar and vector new and delete>.文章中说明了
下压(LIFO)栈:可以动态调整数组大小的实现 import java.util.Iterator; public class ResizingArrayStack<Item> implements Iterable<Item> { private int N = 0; private Item[] a = (Item[]) new Object[1]; public boolean isEmpty() { return N == 0; } public int size() {
