getline();

[hellcoder]

i am confused with syntax
which one is correct

ifstream fileptr;
string line;
fileptr.getline(line,100);
or
getline(fileptr,line)

In this case line 5.

istream::getline() is used when you store data in a char array http://www.cplusplus.com/reference/istream/istream/getline/
When you have an std::string you need to use a global std::getline() http://www.cplusplus.com/reference/string/string/getline/

Assuming you've correctly initialized the ifstream and you've opened a file, the second one would be most correct.

The istream class provides a getline member function as well but it only accepts char *: http://www.cplusplus.com/reference/istream/istream/getline/

What you're looking for is http://www.cplusplus.com/reference/string/string/getline/ which is a part of the string header. To be quite honest, I'm ignorant of what the standard says is the difference between the two as far as result and consequence goes.

[hellcoder]

means there are two getline() function in two different libraries..?
