sf::RenderWindow window(sf::VideoMode(900,900),”My window”); //VideoMode is an object who tell to the window which size take Here is what the above code is Doing: 1. We create a window object called window. 2. We pass two parameters to the constructor of the window object. 3. The first parameter is a sf::VideoMode object. This object holds information…

//example QRandomGenerator::global()->bounded(10);//10 is excluded 0 is included QRandomGenerator::global()->bounded(10, 12);//10 is included 12 is excluded Here is what the above code is Doing: 1. We create a QRandomGenerator object. 2. We use the QRandomGenerator object to generate a random number between 0 and 10. 3. We use the QRandomGenerator object to generate a random number between…
