Question

I’m trying to write a recursive function that does some formatting within a file I open for a class assignment. This is what I’ve written so far:

const char * const FILENAME = "test.rtf";

void OpenFile(const char *fileName, ifstream &inFile) {
    inFile.open(FILENAME, ios_base::in);
    if (!inFile.is_open()) {
        cerr << "Could not open file " << fileName << "\n";
        exit(EXIT_FAILURE);
    }
    else {
        cout << "File Open successful";
    }
}


int Reverse(ifstream &inFile) {
    int myInput;
    while (inFile != EOF) {
        myInput = cin.get();
    }
}

int main(int argc, char *argv[]) {
    ifstream inFile;             // create ifstream file object
    OpenFile(FILENAME, inFile);  // open file, FILENAME, with ifstream inFile object
    Reverse(inFile);          // reverse lines according to output using infile object
    inFile.close();
}

The question I have is in my Reverse() function. Is that how I would read in one character at a time from the file? Thanks.

Answer 1

void Reverse(ifstream &inFile) {
    char myInput;
    while ( inFile.get( myInput ) ) {
       // do something with myInput
    }
}
