I'm new to programming and I had a question for a project I'm working on.

So if I run this code, does the while loop exit after sending the string "world" to the terminal? Or would it exit before that code is ran?

while (conditionalStatement == false) 
{
   std::cout << "hello ";
   conditionalStatement = true;
   std::cout << "world\n";

}

Edit:

When I run the code above it sends hello world to terminal. However, I have another few lines of code that are giving me some different results. Not sure why.

My project is setup basically like this and when I run it, the string "we broke the loop!" Isn't being sent to the terminal when the user inputs 2.

bool something = false;
while (something == false)
{

    std::cout << "choose 2 to break loop.\n";

    int loopbreak;
    std::cin >> loopbreak;

    if (loopbreak == 1)
        {
         std::cout << "were looping!\n";
        } 
    else if (loopbreak == 2) 
        {
        something = true;
        std::cout << "we broke the loop!\n";
        }

}
//continue code

The answer is yes. The condition is only checked at the start of each loop iteration. If you want to end loop execution early, you must execute a break statement.
