The following code is meant to write some text to a file, but it contains an error

ifstream myfile;     // line 1

myfile.open(“greeting.txt”);   //line 2

myfile << “Hello world.\ ”;   //line 3

myfile.close();   // line 4

Which line contains the error in C++?

Solution

Ans.

Line 3 contains error because:
there is no match for ‘operator<<’ when dealing with ifstream.
