while(!FP.eof()) is reading the last data point of the file twice

I'm wondering if someone could point me to the flaw in the following code that uses the while(!FP.eof()) condition to read the input data. This condition is reading the last data point of the file twice. #include #include using namespace std; int main(int argc, char **argv) { double x; ifstream FP("test.d"); //while(!FP.eof()){FP >> x; cout x){cout

Problem reading a bin file

I came from delphi world and now I'm doing my first steps in C++. I'm using C++builder because its ide is like delphi although I'm trying to avoid the vcl. I need to insert new features to an old program that I wrote in delphi and it's a good opportunity to start with c++. well, the problem is: I need to read a binary file according to some structure, all variables of its structure are of type "char" of different sizes. The reading is made ok, but the value that I got of ManVer is his value concatenated with Pieces and Weight and WeightUnit, the value of Pieces is his value and also concatenated with Weight and WeightUnit. This happens with the rest of variables until the last of them, that only has his value. Only when I see the structure with Evaluate/Modify (Ctrl +F7 on windows) the result is the one that I expect to get I hope that you can help me... here's the code: -------------- ifstream _fileStream; TStructure_V250_Data _buffer250; //open the file... char* _fName = new char[_fileName.Length() +1]; strcpy(_fName, _fileName.c_str()); _fileStream.open(_fName, ios::binary); delete [] _fName; //read data... _fileStream.read((char*)&_buffer250, sizeof(_buffer250)); --------------------------- _buffer250 structure is too long, i only show you a piece --------------------------- typedef struct _Structure_V250_Data { char ManVer[4]; char Pieces[3]; char Weight[5]; char WeightUnit[2]; //... //... //... } TStructure_V250_Data;

Strange problem reading unsigned chars from an ifstream

Hi , Sorry if I'm just being daft, but I can't immediately see why the following code won't work. It's supposd to read in the characters from blah.raw one by one, then output the textual representation of them to blah.txt, with spaces between each. The end result is almost right, but it arbitrarily misses out a couple of values. Please could you tell me if I'm doing something obviously wrong (Or...failing that, might I have a minor bug in my library implementation I'm assuming it's my own fault for the moment, but it has crossed my mind...) Cheers, Stu (I'm trying to do this as a quick(!) way of getting a heightmap into MATLAB to render a surface rather than writing a heightmap viewer in OpenGL, for what it's worth, and it's missing one pixel value each on the first and last lines.) #include int main() { std::ifstream ifs("blah.raw", std::ios::binary); std:fstream ofs("blah.txt"); unsigned char c; while(ifs >> c) { ofs

reading variables from a stream(beginner)

hello, what i am trying to do is set up a loop that grabs multiple variables from an input file. my question is, is there a built in function in the istream class that can grab multiple values on one line. such as 60 40 10 10 all getting put into different variables. the problem i am having is that there is other data in the file that i do not want to do this to. can i set the get for only the first line of data from the file.

File reading problem

Hi! I have a program with a class that needs to be able to write itself to a file in clear text format. The file has two integers and vector of struct objects. The struct has a string that can consist of one or more words and a few integers. I'm able to create the file properly, as confimed by viewing it in a text editor, but something goes wrong when I tried to read it. I've made a test program illustrating the problem: #include #include #include #include using namespace std; struct s_t { s_t() {} s_t(const string& si, int xi, int yi) : s(si), x(xi), y(yi) {} string s; int x, y; friend ostream& operator(istream& is, s_t& rhs); }; ostream& operator> x >> y; { s_t temp; while (in >> temp) vec.push_back(temp); } in.close(); cout

Problems with file reading and writing

, I've encountered a strange problem which I can't seem to explain. I've written a simple C++ class that deals with a certian binary file. In one of the methods there, I wish to update a file - namely to read a certain field whose offset I know, and then write to another field, whose offset I also know. In order to read the data, I first use file.seekg(offset, ios::beg), and then a read command; I've checked the variable, and this part is executed as it should be. The problem is with the writing. To place the head where I want it, I use a file.seekp(offset, ios::beg) statement. After this statement, regardless of what the value of 'offset' is, file.tellp() always returns '-1'. The file was opened using the statement: file.open(FileName.c_str(), ios::in | ios:ut | ios::binary) where FileName is a string. The reading goes smoothly and returns the correct values, so I doubt there's a problem with the actual opening of the file.

reading in comma delimited file into array

hi- I want to read in a text file that is comma delimited with floating point values. I'm confused whether ifstream or fopen is the correct format to use for this. if I use ifstream, how to I read in one line at a time into the array also is there a way to get the total number of lines in the text file so I know how big to set the array the text file looks like 1.555,2.555 1.948,33.44 etc, and I just want to put the values in an array with two columns. it sounds pretty simple but I haven't been able to figure out how to do it yet. so far the code is ifstream input("data_record.txt") if (input.fail()){ cout

multithreading with each thread in a separate class instance vs. in aC-style kernel thread calls in C++
