程序要求：找出字符串sentence 中，最少字符单词 和 最多字符单词
问题：下面是我写的代码，感觉复杂了点，功能好像实现了。大家帮忙写出好点的程序，我学习了，我初学c++

#include <iostream> 
#include <string> 
#include <vector> 
using namespace std; 

int main() 
{ 
    string line1 = "We were her pride of 10 she named us:"; 
    string line2 = "Benjamin, Phoenix, the Prodigal"; 
    string line3 = "and perspicacious pacific Suzannne"; 
    string sentence = line1 + ' ' + line2 + ' ' + line3; 

    // 测试下字符串长度    
    cout << line1.size() << endl; // 37 
    cout << line2.size() << endl; // 31 
    cout << line3.size() << endl; // 34 
    cout << sentence.size() << endl; // 104 
    string::size_type  size = sentence.end() - line3.begin(); 
    cout << size << endl; // 648 
    
    // 以line1为例，测试下输出 
    string::iterator ster = line1.begin(); 
    int count = 0; 
    for (ster = line1.begin(); ster != line1.end(); ++ster) 
    { 
        cout << *ster; 
        count++; 
    }
    cout << count << endl; // 37, 字母+ 空格 + : = 37个 
    
    // pos代表空格在 sentence字符串中的下标位置 
    string::size_type pos = 0; 
    int space = 0; 
    vector <int> ivec; // ivec 存储空格在字符串中的下表位置 
    while ((pos = sentence.find_first_of(' ', pos)) != string::npos) 
    {
          ++space; 
          ivec.push_back(pos); 
          cout << pos << " "; 
          ++pos; 
    } 
    pos = 0; 
    ivec.push_back(sentence.size() - pos); // sentence 结束那里添加个空格 
    cout << sentence.size() - pos << endl; 
    cout << "There is: " << space + 1 << " characters" << endl; // line1: 9; line2: 4; line3: 4; sentence: 9 + 4 + 4 
    
    // ivec2 存储相邻空格下标 的差值，为了统计单词 字符个数的需要

楼主不会使用字符串流吗？

[太乙]

#include<iostream>
#include<string>
#include<sstream>
using namespace std;
int main()
{
	string s = "We were her pride of 10 she named us:\nBenjamin, Phoenix, the Prodigal\nand perspicacious pacific Suzannne";
	stringstream ss,ss2;
	ss<<s;
	string line,word;
	string maxstr,minstr(10,'1');
	while(getline(ss,line))
	{
		ss2<<line;
		while(ss2>>word)
		{
			if(word.length()>maxstr.length())
				maxstr = word;
			if(word.length()<minstr.length())
				minstr = word;
		}
		ss2.clear();
	}
	cout<<maxstr<<endl;
	cout<<minstr<<endl;
	return EXIT_SUCCESS;
}

楼上的定义 iterator it 的时候，应该放在for 循环外面吧
试了你写的程序，比我的好多了，谢谢
问题解决了，结贴
