Question

(Please Use c++ code)

1. For this assignmaent all you need to do is fix the program and make sure it compiles?

#include <iostream>
#include <string>
#include <vector>

using namespace std;

class Tweet
{public:
Tweet(string s, string m);
string getSubject();
string getMessage();
void changeMessage(string m);
private:
string subject;
string message;
};

Tweet::Tweet(string s, string m)
{subject = s;
message = m;
}

string Tweet::getSubject()
{return subject;
}

string Tweet::getMessage()
{return message;
}

void Tweet::changeMessage(string m)
{message = m;
}

class Twitter
{public:
Twitter();
void addTweet(Tweet newmessage);
Tweet gettweet(string subject);
private:
vector<Tweet> messages;
};

Twitter::Twitter()
{
}

void Twitter::addTweet(Tweet newmessage)
{messages.push_back(newmessage);
}

Tweet Twitter::gettweet(string subject)
{for(int i=0; i<messages.size();i++)
{if(messages[i].getSubject() == subject)
{return messages[i];
}

}
return Tweet();
}

int main()
{Twitter t = Twitter();
Tweet s = Tweet("FINISHED MIDTERM","ACED IT");
t.addTweet(s);
}

Explanation / Answer

#include <iostream>

private:
string subject;
string message;
};

Tweet::Tweet(string s, string m)
{subject = s;
message = m;
}

Tweet::Tweet()

{

}

string Tweet::getSubject()
{return subject;
}

string Tweet::getMessage()
{return message;
}

void Tweet::changeMessage(string m)
{message = m;
}

class Twitter
{public:
Twitter();
void addTweet(Tweet newmessage);
Tweet gettweet(string subject);
private:
vector<Tweet> messages;
};

Twitter::Twitter()
{
}

void Twitter::addTweet(Tweet newmessage)
{messages.push_back(newmessage);
}

Tweet Twitter::gettweet(string subject)
{for(int i=0; i<messages.size();i++)
{if(messages[i].getSubject() == subject)
{return messages[i];
}

}
return Tweet();
}

int main()
{Twitter t = Twitter();
Tweet s = Tweet("FINISHED MIDTERM","ACED IT");
t.addTweet(s);
}
