- Do the given code by using a flag-controlled while loop - Idea: - Take a flag of type bool (the meaning if this flag is: if E is pressed, then it is True. If any other char is pressed then it is False) - Initially make it False - take an input as char - check if the input is ' E '. If so, then change the flag to True - write the while loop ad shown in the slide - take another input as char inside the while loop - check if the input is ' E '. If so, then change the flag to True - so, next time the while loop will terminate - use clear screen command/function to clear the screen, then show the output, then show the menu again. Search internet to see how to clear screen in C++ - Sample code with sentinel controlled while loop is given below - Sample output given below - Give your code below - Give output for all options (+, - E, default)
