title: How to execute a piece of code only once?
body: <p>I have an application which has several functions in it. Each function can be called many times based on user input. However I need to execute a small segment of the code within a function only once, initially when the application is launched. When this same function is called again at a later point of time, this particular piece of code must not be executed. The code is in <b>VC++</b>. Please tell me the most efficient way of handling this.</p>
