Displaying a Message in C++
C++ is a widely used general purpose programming language developed by Bell Labs and Bjarne Stroustrup. The C++ language is an extension of the original C language, and much of the original C syntax is inherited. The MessageBox function in C++ allows for a standard Windows dialog box to be displayed along with a title, body text and interactive buttons. The second argument defines the actual message text. The third argument defines the message box title. The final argument defines the interactive buttons.
