这可能是一个非常简单的问题,但请原谅我,因为我是新人.这是我的代码:

#include <iostream>
#include <string>
#include <sstream>
using namespace std;

int main ()
{ 
   string name;
   int i;
   string mystr;
   float price = 0;

   cout << "Hello World!" << endl;
   cout << "What is your name? ";
   cin >> name;
   cout << "Hello " << name << endl;
   cout << "How old are you? ";
   cin >> i;
   cout << "Wow " << i << endl;

   cout << "How much is that jacket? ";
   getline (cin,mystr);
   stringstream(mystr) >> price;
   cout …
