Any one here good at C++

1. while ( getline ( infile, buffer ) ) {
   // Process the line
2. }

I'm reading a file from the stream to display in the console, but it only displays the first line how do I display the other lines?

C isn't my strong point, and specific C functions are even less so.

If getline returns an int > 1 whenver it successfully executes, then it should work.

If it doesn't then that is why it isn't running past the first loop.

Maybe something about going to next line?, skipping newline and carriage returns? just a random guess

Well thanks for trying the problem is that it can only display the first line how do I display ALL the lines?

you might want to change it to while (!infile.eof()) the call get line within the loop rather than doing it in a conditional.

int main()
{

string name;

cout << "Please enter the filename of the encoded message:";

getline(cin,name);


ifstream infile;
infile.open(name.c_str());

if (infile.fail()) {
cout << name << " fail to open." << endl;
exit(1);
}


cout << name << endl;

cout << " File successfully opened" << endl;

string buffer;
getline(infile, buffer);

while ( infile.eof() ) {

cout << buffer << endl;

}

return 0;
}

This only displays 1 line how do I get the other lines?

[Dan02]

probably because in your while not eof loop you're never changing the value in buffer,

should it not be while( !inline.eof()) as well?

how about something likke

int main()
{

string name;

cout << "Please enter the filename of the encoded message:";

getline(cin,name);


ifstream infile;
infile.open(name.c_str());

if (infile.fail()) {
cout << name << " fail to open." << endl;
exit(1);
}


cout << name << endl;

cout << " File successfully opened" << endl;

string buffer;
getline(infile, buffer);

while ( !infile.eof() ) {

cout << buffer << endl;
getline(infile, buffer);

}

return 0;
}

Been awhile since i did any code though so maybe it sucks

should be

 
while( !infile.eof())
{
getline(infile, buffer);
cout << buffer << endl;
}

10 PRINT "Do your own homework!"
20 GOTO 10

[kermitology]

Yeah, do your own work!

I still would have suggested the use of finding the EOF. You'd crash if you didn't anyways.

[Rathji]

Yeah, EOF is the way I have always done it. I just assumed getline() was some library use of while(!EOF) but I have zero knowledge of anything that is not the most basic c standard library.

Or try LOL Code

Hai
can has stdio?
Plz open file "lolcats.txt"?
	Awsum thx
		visible file
	o noes
		invisible "error!"
kthxbye
