I am trying to print data to a file; however, the file that is created is empty, and nothing seems to be printed to it. I know that the file stream is open and good because my cout statements are printing what i am expecting, but for some reason, the write-file is blank when I check. Any solutions would be appreciated. Thanks.
void printToStream(std::ofstream &fileStream, std::string printString) {
if (fileStream.is_open() && fileStream.good()) {
std::cout << "printing to file " << std::endl;
std::cout << printString;
fileStream << std::flush;
fileStream << printString;
} else {
printError("File not open");
}
}
Move std::flush
to the end of the output.
For example like this:
fileStream << printString << std::flush;
