C++Primer习题6.12

编写一个小程序，从标准输入读入一系列 string 对象，寻找连续重复出现的单词。程序应该找出满足以下条件的单词的输入位置：该单词的后面紧跟着再次出现自己本身。跟踪重复次数最多的单词及其重复次数。输出重复次数的最大值，若没有单词重复则输出说明信息。例如，如果输入是：

#include<iostream>
#include<string>
using std::cin;
using std::cout;
using std::endl;
using std::string;

int main()
{
	string s, stemp, sresult;
	int count = 0;
	int counttemp = 0;
	//
		//控制x,x,y,y,z,z的情况，这种情况不会被判为重复
	int initial = 0;
	int i = 0;
	//
	while (cin >> s)
	{
		//string stemp;
		if (stemp.empty())
		{
			stemp = s;
			counttemp = 1;
			count = 1;
			sresult = s;
			//initial = 1;
			cout << "初始化各值" << endl;
			//sresult=s;
		}
		else if (stemp == s)
		{
			++counttemp;
			//++initial;
			//++count;
			cout << "与上一次一样" << endl;
			cout << "couttemp=" << counttemp << endl;
			//cout << "initial=" << initial << endl;
			if (count<counttemp)
			{
				count = counttemp;
				sresult = stemp;
				cout << "count=" << count << endl;
			}

		}
		else 
		{
			
			cout << "与上一次不一样" << endl;
			//sresult=stemp;
	/*		if (count<counttemp)
			{

				count = counttemp;
				sresult = stemp;
				cout << "count=" << count << endl;
			}*/
			stemp = s;
			counttemp = 1;
			while (i != 1)
			{
				initial = count;
				i++;
			}
		}
		//else
		//{
		//	if (count<counttemp)
		//	{
		//		count = counttemp;
		//		sresult = stemp;
		//	}
		//	//stemp=s;
		//	//counttemp=0;
		//}
	}

	/*if (flag==0)
	{
		cout << "count:" << counttemp << "string:" << sresult << endl;
	}
	else if (flag==1)
	{
		cout << "count:" << count << "string:" << sresult << endl;
	}*/
	if (initial == count)
	{
		cout << "没有元素过于重复" << endl;
	}
	else
		cout << "count:" << count << "string:" << sresult << endl;
	system("pause");
	return 0;
