  为什么编译可以通过  但是一运行就错误，觉得/* 之间那句有问题，但是考虑后面要对字符长度进行排序，不这样不好办，请各位高手指点，非常感谢。

#include <iostream>

using namespace std;

int main()
{
    vector<string> passage;

    cout << "Please input one passage:" << endl;

        passage.push_back(x);

    cout << "The original passage is:" << endl;

        cout << passage[i] << '\n';
    cout << flush;

    vector<double> numble;
    for( size_t i=0; i!=passage.size(); ++i )
        numble.push_back( passage[i].size() );

    for( size_t i=0; i!=numble.size(); ++i )
        cout << numble[i] << '\n';
    cout << flush;

    sort( numble.begin(), numble.end() );

    size_t ms;
    for( ms=0; passage[ms].size()!=numble[0]; ++ms );
    cout << "The shortest words are:" << passage[ms] << endl;

    size_t ml;
    for( ml=0; passage[ml].size()!=numble.back(); ++ml );
    cout << "The longest words are:" << passage[ml] << endl;

    return 0;
}
/*
输入：ab abc a abcdef abcd
输出：
The original passage is:
ab
abc
a
abcdef
abcd
2

The shortest words are:a
The longest words are:abcdef

非常感谢  但问一下 为什么最后输出条件是passage[ms].size()!=numble[0]; 而不是 passage[ms].size()==numble[0];
还有如果有多个字符串长度相等，你的程序好像只能输出第一个。
