Problems in Counting Lines in Text File

A Portion of my file read code to count lines:

CPP / C++ / C Code:

string temp;
.
.
.
  while(!in.eof())
    {
    	if (!(in>>temp)) break;
      	else
      	{
      	 	if(temp=="\n")
          	{
          	 linecount++;
          	}
                cout<<"Line No: "<<linecount<<"\n"<<endl;
        }

The linecount stays at a permanent 0

You should be looking for '\n' as a character and not as a "\n" which is string notation.

change your inner if condition to

CPP / C++ / C Code:

if(temp=='\n')
            { .......

... and in.eof() will 'read' one extra character or line.

Another option is to read the file using getline() and count how many times it read rather than char by char testing each one.
