随机产生10个100以内的整数建立一个顺序栈，从栈顶到栈底依次显示栈内元素；从键盘输入出栈元素个数 n (1<= n <=10)，将 n 个元素依次出栈并显示出栈元素，再显示此时栈顶元素。

#include <iostream>  
#include <cstdlib>  
#include <ctime>  
using namespace std;
const int StackSize = 100;
template <typename DataType>
class SeqStack {
public:SeqStack() : top(-1) {} // 构造函数，初始化栈顶为-1  DataType data[StackSize];int top;void Push(DataType x);DataType pop();int Empty();void GenerateAndPushRandomNumbers(); // 生成随机数并压入栈  void PopAndDisplay(int n); // 出栈并显示n个元素  void DisplayTop(); // 显示栈顶元素  
};
template <typename DataType>
void SeqStack<DataType>::Push(DataType x) {if (top == StackSize - 1) throw "Overflow";data[++top] = x;
}
template <typename DataType>
DataType SeqStack<DataType>::pop() {if (top == -1) throw "下溢";return data[top--];
}
template <typename DataType>
int SeqStack<DataType>::Empty() {return top == -1;
}
template <typename DataType>
void SeqStack<DataType>::GenerateAndPushRandomNumbers() {srand(time(nullptr)); // 初始化随机数种子  for (int i = 0; i < 10; ++i) {int randomNumber = rand() % 100; // 生成0到99的随机数  Push(randomNumber);}
}
template <typename DataType>
void SeqStack<DataType>::PopAndDisplay(int n) {for (int i = 0; i < n; ++i) {DataType poppedElement = pop();cout << "Popped element: " << poppedElement << endl;}
}
template <typename DataType>
void SeqStack<DataType>::DisplayTop() {if (!Empty()) {cout << "Top element: " << data[top] << endl;}else {cout << "Stack is empty." << endl;}
}
int main() {SeqStack<int> stack;stack.GenerateAndPushRandomNumbers(); // 生成随机数并压入栈  // 显示栈内元素  cout << "Elements in the stack (from top to bottom):";for (int i = stack.top; i >= 0; --i) {cout << " " << stack.data[i];}cout << endl;int n;cout << "Enter the number of elements to pop (1-10): ";cin >> n;stack.PopAndDisplay(n); // 出栈并显示元素  stack.DisplayTop(); // 显示栈顶元素  return 0;
