1、精选优质文档-倾情为你奉上堆栈、队列、字符串匹配相关算法C+实现一、堆栈.cpp部分#include#includestack.husing namespace std;int main () int c; cout输入堆栈大小:c;astack STA1(c); int t; cout输入栈元素:endl;for(int i=0;it;STA1.push(t); int ch;cout1:弹栈endl;cout2:获取栈顶元素:endl;cout3:入栈元素:endl;cout4:输出栈中元素;endl;cout5:重设栈的大小:ch;while(ch!=-1)switch(ch)case
2、1:int re1; STA1.pop(re1); cout删除栈顶元素:re1endl; break;case 2:int re2 ; STA1.peek(re2); cout获取栈顶元素:re2endl; break;case 3:int r; cout输入入栈元素:r; STA1.push(r); break;case 4:STA1.print();break;case 5:int s; cout输入新的大小:s; STA1.setsize(s); break;cout还需要什么帮助吗?ch;if(ch=-1)cout谢谢使用endl;return 0;.h部分#includetempl
