Make sure that you #include <fstream>. Recall that ifstream is in namespace std, so you would need "using namespace std;" or "using std::ifstream" or explicitly write std::ifstream everywhere. Igor Tandetnik Tuesday, April 17, 2012 8:36 PM ...

the first one is in a C-type way, contents of both are same, but functions in the first one are not in namespace std!! 15.when do comparison in for() statement, why != is preferred than < ? NOT EQUAL can be used to compared index array and iterators as well. ...
