代码：全选

#include <iostream>
#include <stdio.h>

using namespace std;

int main() {
 
   cout << "Content-type:text/html\n\n";
   cout << "<html>\n";
   cout << "<head>\n";
   cout << "<title>Hello World the first CGI</title>\n";
   cout << "</head>\n";
   cout << "<body>\n";
   cout << "<h2>Hello World! the first CGI program</h2>\n";
   cout << "</body>\n";
   

    return 0;
}

代码很简单，却踏了新手两个经典坑：
1.在windows客户端编译好的二进制不能直接上传到linux服务端；
2.cout << "Content-type:text/html\n\n";这句一定是两个“\n”,否则报500错误，这个问题很隐蔽。
