Question

我正在用C ++实验CGI。我知道有些库可以处理基本的东西，但是为了知道最新情况，我一直在尝试使用字符串数据类型解析stdin ---＆gt;使用'=和＆amp;'标记化然后push_back进入向量。在后一步，我收到分段错误。下面给出的是我使用cin＆gt;＆gt;的程序。获取用户输入等等..

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <vector>
#include <algorithm>
#include <string.h>
using namespace std;
int main()
{

    vector <string> stuff(0);
    vector<string>::iterator it;
    char* bufferchar;
    string buffer;


    char str[size];
    cout<<"Content-type: text/html\n\n"
      <<"<html>"
      <<"<head>"
      <<"<title>CGI SCRIPT</title>"
      <<"</head>"
      <<"<body>"
    fgets(str,20,stdin);      //20 is expect size of content from html form
    puts(str);

    cout<<"<p>Now to break this guy apart";
    int x=0;
    bufferchar = strtok(str,"&=");
    buffer+=bufferchar;
    stuff.push_back(buffer);
    while(bufferchar!=NULL){
      cout<<bufferchar<<'\n'<<'\n';
      bufferchar=strtok(NULL,"&=");
      buffer+=bufferchar;
      stuff.push_back(buffer);
      }
    cout<<"<br>ok does the vector iterate ?";
    for (it=stuff.begin();it!=stuff.end();++it){
      cout<<*it;
      cout<<"<br> ok man, next <br><br>";
    }
    cout<<"</body>";
    cout<<"</html>";
}

无法对字符串进行标记并传递给向量<string> </string>
