哪个大神帮我看看为什么我运行不了这段代码（初学者）

#include <iostream>
using namespace std;

int main()
{
string outside();
cout<<"do you like going outside? "<<endl;
getline(cin, outside);
string food();
cout<<"do you like fish or pork? "<<endl;
getline(cin,food);
string weather();
cout<<"Do you like sun or rain? "<<endl;
getline(cin,weather);

if (outside="yes"&&food="pork"&&weather="sun")
{
  cout<<"you are a lot like a dog"<<endl;
}
else if(outside="yes"&&food="pork"&&weather="rain")
{
  cout<<"you are more like a dog"<<endl;
}
else if(outside="yes"&&food="fish"&&weather="rain")
{
  cout<<"you are more like a cat"<<endl;
}
else if(outside="no"&&food="fish"&&weather="rain")
{
  cout<<"you are alot like a cat"<<endl;
}
else if(outside="no"&&food="fish"&&weather="sun")
{
  cout<<"you are more like a cat"<<endl;
}
else if(outside="no"&&food="pork"&&weather="sun")
{
  cout<<"you are more like a dog"<<endl;
}
else{
  cout<<"you are a human"<<endl;
}
}

1.了解一下如何定义std::string变量
2.if语句中判断条件的 “=”和“==”是不同的
3.main函数的返回值
