#include <fstream>

int main() {
std::ofstream outFile("example.txt");
outFile &lt;&lt; "Hello, file!" &lt;&lt; std::endl;
outFile.close();
std::ifstream inFile("example.txt");
std::string line;
while (std::getline(inFile, line)) {
    std::cout &lt;&lt; line &lt;&lt; std::endl; // Output: Hello, file!
}
inFile.close();
return 0;
}
