#includeusing namespace std; int main() { // open a binary file for writing ofstream outputFile("output.bin", ios::binary); // write binary data to the file int num1 = 10; double num2 = 3.14159; outputFile.write(reinterpret_cast (&num1), sizeof(num1)); outputFile.write(reinterpret_cast (&num2), sizeof(num2)); // close the file outputFile.close(); return 0; }
#includeThis example opens a binary file for reading, reads an integer and a double from the file, and then prints the values that were read. Again, the `reinterpret_cast` operator is used to convert pointers to the data into `char*` pointers that can be passed to the `read` function. The BFile class is not a standard C++ class and is not part of the standard library. It is likely a custom class provided by a third-party library or framework.using namespace std; int main() { // open a binary file for reading ifstream inputFile("input.bin", ios::binary); // read binary data from the file int num1; double num2; inputFile.read(reinterpret_cast (&num1), sizeof(num1)); inputFile.read(reinterpret_cast (&num2), sizeof(num2)); // close the file inputFile.close(); // print the values that were read cout << "num1 = " << num1 << endl; cout << "num2 = " << num2 << endl; return 0; }
