I have to write a C++ program that opens a file and counts all the whitespace separated words in that file. I am using GNU C++ compiler on Mac, using the terminal instead of an IDE. What command do I use to link a file to be opened in my C++ program at the command line? And I don't have to use an ifstream object right? Since I am not really opening up a file from within my program? Kind of confused... |

Usually you don't link the file to your program, you open it with ifstream. ifstream does not require the file to be "within [your] program." Though I'm pretty sure you can include any data you want in your .exe, I just don't have a clue how to do it. I'm sure <a href=http://www.cplusplus.com/doc/tutorial/files/>this</a> could explain it a lot better. |

Thanks for the reply, but the reason I ask is because this program is supposed to be able to open ANY text files within the same directory. All the example codes I have seen only opens a specific file. This is supposed to be the answer: #include <iostream> #include <string> using namespace std; int main() { int nwords = 0; string word; while (cin >> word) { ++nwords; } cout << "Number of words = " << nwords << endl; } But I don't know how to execute that by linking a file to it. |

umm quick question whats the diffference between #include <iostream> and #include <iostream.h>, oh and what about #include <conio.h> cause i learned these with my teacher last year but she didint fully explain what they were for |

Never mind, I figured it out! For anyone who cares, I just need to link the text file to the a.out file, with this command: ./a.out < textfile.txt And for Monduman11: #include <iostream.h> is equal to #include <iostream> using namespace std; Something to do with the transition from C to C++ and the way headers files are included. |
