Two of the menu options (#2 and #3) are unfinished, and you need to complete the code necessary to write to and read from a binary file. You will need to read through the code to find the functions that are called by these options, and then supply the missing code. Please help me get menu 2 and 3 to display properly. you have been provided the .cpp and .h file, you cannot edit, but instead add onto the code that was given: .cpp file: // Corporate Sales Data Output using namespace std; #include #include #include #include "HeaderClassActivity1.h" int main() { Sales qtrSales[NUM_QTRS]; while (true) { cout << "Select an option: " << endl; cout << "1.
