嵌套vector怎么输出

[modicum_tk]

#include<iostream>
#include<fstream>
#include<vector>
#include<string>

using namespace std;


struct PART
{

string id;
string seq;
vector<string> andl;
};

struct PART info;

struct HEAD
{

string id;
vector<INFO> Info;
};

struct HEAD head;

int main()
{

string str, src;

string filename = "456.txt";

ifstream infile(filename.c_str());


while(getline(infile,str))

{

string::size_type m = str.find('\t');

src = str.substr(0,m);

if( src == "@part" )

head.Info.push_back(info);

if( src == "@l" )

info.andl.push_back(str.substr(m));

if( src == "@seq" )

info.seq = str.substr(m);

if( src == "id" )

info.id = str.substr(m);

}

return 0;

}


怎么输出。 把结构体中的数据全部输出来



@part
@id 2
@seq 23
@l 553627 16591772 17567667 1

@part
@id 2
@seq 24
@l 553627 16591771 17567695 1
@l 553627 17567695 17567666 1

@part
@id 2
@seq 25
@l 553627 16591770 17567666 1
要这样的效果

不要用嵌套的vector，效率会非常低。

你不用再发了，晚上我帮你写一个好了。

把456.txt里面的内容也贴出来。

不错！
