我的教授给了我一个简单的HTML表单的作业，提交到CGI程序（使用c ++ gnu库cgicc），无论我尝试多少次修复，每当我在HTML页面中调用该程序时，我都会得到服务器错误500：标题之前的脚本输出结束：submit.cgi。
这是我的submit.cpp（编译生成submit.cgi的文件）
#include<iostream>
#include<vector>
#include<string>
#include"cgicc/Cgicc.h"
#include"cgicc/HTTPHTMLHeader.h"
#include"cgicc/HTMLClasses.h"
using namespace std;
using namespace cgicc;
int main(int argc, char** argv)
{
Cgicc cgi;
cout << HTTPHTMLHeader() << endl; //Header
cout << html() <<head (title("Submitted Form Data")) << endl; // Head
cout << body() << endl; //<body>
//Submitted Elements are Printed
form_iterator rname = cgi.getElement("restaurant_name");
if(rname != cgi.getElements().end())
{
cout << "Restaurant Name: " << **rname << "<br>" << endl;
}
form_iterator city = cgi.getElement("city");
if(city != cgi.getElements().end())
