I'm trying to write a program that simulates a HDLC (high-level data-link control) flag. The program will received characters from the keyboard until it detects the flag. Upon detection of the first flag, the program will continue to receive characters from the keyboard until a flag is detected again. The output of the program will be the data between the two flags. The constraint for this program is the person has to enter from the keyboard WITHOUT hitting the "enter" key. That means as soon as he or she types a character, the program will start to process the data. I have all the different loops required and I'm using array strings to compare with the flag and save the output to a different array for output. But I can't figure out the C++ command that allows the person to enter characters WITHOUT having to hit the "enter" key. I thought cin.get() will do the trick but this command still requires the user to hit the "enter" key.
Sorry, but in standard C++ this is impossible to do. In standard C++ all input is line buffered, that means that the input is not actually made available to your program until the user finsihes the line

Many modern programming languages support the concept of a property -- a class member that combines characteristics of both a data member and a method. These are sometimes called "smart fields" because you can add logic that is applied automaticall…
The viewer will learn how to pass data into a function in C++. This is one step further in using functions. Instead of only printing text onto the console, the function will be able to perform calculations with argumentents given by the user.
