Why isn't my program doing anything at all? - c++

Question

I'm sorry for the vague title, but I don't know what else to say.
Here is my program:
#include <iostream>
#include <iomanip>
#include <sstream>
#include <string>
#include <fstream>
#include <vector>
using namespace std;
int
main (int argc, char **argv)
{
//string fin;
string ttl, dscp, ext;
string west = "w";
string east = "e";
string north = "n";
string south = "s";
int numRooms;
//string argv[1] = filename;
class Room
{
public:string title;
string description;
string exits;
int exitWest = -1;
int exitNorth = -1;
int exitEast = -1;
int exitSouth = -1;
int numExits;
};
ifstream fin;
fin.open (argv[1]);
//cin.ignore();
int t = 0;
while (fin)
{
string tilde;
string tester;
tester = "~";
cin >> tilde;
if (tilde == tester)
{
t = t + 1;
}
(numRooms = t / 3);
}
Room *roomArrayPtr = new Room[numRooms];
fin.clear ();
while (fin)
{
for (int l = 0; l < numRooms; l++)
{
getline (fin, ttl, '~');
roomArrayPtr[l].title = ttl;
getline (fin, dscp, '~');
roomArrayPtr[l].description = dscp;
getline (fin, ext, '~');
stringstream sin;
sin << ext;
string x;
int y;
while (sin >> x >> y)
{
if (x == west)
{
roomArrayPtr[l].exitWest = y;
}
if (x == south)
{
roomArrayPtr[l].exitSouth = y;
}
if (x == north)
{
roomArrayPtr[l].exitNorth = y;
}
if (x == east)
{
roomArrayPtr[l].exitEast = y;
}
}
sin.clear ();
int numext;
numext = (ext.size ()) / 3;
roomArrayPtr[l].numExits = numext;
}}
//(read in file again populate roomarrayptr w while loop and getline)
//roomArrayPtr[index].title = line;
//roomArrayPtr[index].description=line;
//close files, while loop that reads in user input from stdin, delete pointers w (delete[] roomArrayPtr;)
//if (exitsarray[i].size() > 2){
char command;
char newcommand;
cout << ">";
cin >> command;
int currentroom = 0;
int newroom;
bool keepgoing = true;
//string dir1;
while (keepgoing)
switch (command)
{
// stringstream ss;
case 'l':
cout << roomArrayPtr[currentroom].title << endl;
cout << roomArrayPtr[currentroom].description << endl;
cout << endl;
//if (roomArrayPtr[currentroom].numExits < 2) {
cout << "Exits: ";
if (roomArrayPtr[currentroom].exitWest > -1)
{
cout << "w";
}
if (roomArrayPtr[currentroom].exitNorth > -1)
{
cout << "n";
}
if (roomArrayPtr[currentroom].exitSouth > -1)
{
cout << "s";
}
if (roomArrayPtr[currentroom].exitEast > -1)
{
cout << "e";
}
/*else {
cout << "Exits: " ;
for (int k = 0; k < numExits; k++){
cout << exitdirection << " ";
}
}*/
//string newcommand;
cin >> newcommand;
//int newroom;
switch (newcommand)
{
case 'w':
if (roomArrayPtr[currentroom].exitWest == -1)
{
cout << "You can't go WEST!" << endl;
}
else
{
newroom = roomArrayPtr[currentroom].exitWest;
cout << "You moved WEST." << endl;
}
break;
case 'e':
if (roomArrayPtr[currentroom].exitEast == -1)
{
cout << "You can't go EAST!" << endl;
}
else
{
newroom = roomArrayPtr[currentroom].exitEast;
cout << "You moved EAST." << endl;
}
break;
case 'n':
if (roomArrayPtr[currentroom].exitNorth == -1)
{
cout << "You can't go NORTH!" << endl;
}
else
{
newroom = roomArrayPtr[currentroom].exitNorth;
cout << "You moved NORTH." << endl;
}
break;
case 's':
if (roomArrayPtr[currentroom].exitSouth == -1)
{
cout << "You can't go SOUTH!" << endl;
}
else
{
newroom = roomArrayPtr[currentroom].exitSouth;
cout << "You moved SOUTH." << endl;
}
break;
}
break;
case 'q':
keepgoing = false;
return 0;
break;
currentroom = newroom;
}
}
Whenever I run it, it compiles, but nothing happens. I tried putting in some random cout << "testing1" "testing2" scattered throughout, but none of those even showed up. I put it immediately after the { after int main and it still didn't show up. What's going on?

Answer 1

you are reading the wrong file
int t = 0;
while (fin)
{
string tilde;
string tester;
tester = "~";
cin >> tilde; <<<<===== i assume you mean fin
if (tilde == tester)
{
t = t + 1;
}
(numRooms = t / 3);
}
