使用标准C库堆栈类时,堆栈的最大大小是多少？

By default,if no container class is specified for a particular stack class instantiation,the standard container deque is used.

由于系统或库实现限制,可以使用max_size功能找到：

// deque::max_size
#include <iostream>
#include <deque>

int main ()
{
  unsigned int i;
  std::deque<int> mydeque;

  std::cout << mydeque.max_size(); // 1073741823

  return 0;
}

Example

作为示例值,它在链接的程序上返回1073741823.

你还应该记住：

This is the maximum potential size the container can reach due to known system or library implementation limitations,but the container is by no means guaranteed to be able to reach that size: it can still fail to allocate storage at any point before that size is reached.

即这些是理论设计限制,您不应该在正常使用场景中接近这些限制.其他容器也有类似的考虑因素.
