Strange issue with cout
- by ben
After reading from a text file, and storing it into a string, I tried to pass this message into another function that will print it out.
This is what it looks like:

void insert (int id, string message){
cout << "Inserting " << message << " at" << endl;
}
Somehow the message behind the string overrides the message.
But once I removed the " at" after message, it worked as expected. http://imgur.com/JdHPPmi
void insert (int id, string message){
cout << "Inserting " << message << endl;
}
I somehow suspect the problem came from stringstream, but i couldn't find out where.
Here's the code that read from file
vector <string> line;
fstream infile;
string readLine, tempLine, action, tempLine1;
int level, no;
infile.open(fileName.c_str(),ios::in);
int i = 0;
while (!infile.eof())
{
getline (infile, readLine);
line.push_back(readLine);
}
infile.close();
line.pop_back();
for (int i = 0; i < line.size();i++)
{
stringstream ss (line.at(i));
getline (ss, action, ' ');
if (action == "init")
{
// some other work here
}
else if (action == "insert")
{
tempLine = line.at(i);
ss >> no;
stringstream iline(tempLine);
getline (iline, tempLine1, ' ');
getline (iline, tempLine1, ' ');
getline (iline, tempLine1, '\n');
Insert (no, tempLine1);
}
Since my file has different kinds of actions, here is what test.dat contains:
insert 0 THIS IS A TEST
edit: When i did file.txt, it came out as something like this.
Inserting THIS IS A TEST
at
Inserting THIS IS TEST NO 2
