Explanation
- Class Definition (
Firework):- Private Members:
xandy: Coordinates for the firework’s launch position.exploded: A boolean flag indicating whether the firework has exploded.
- Public Methods:
Firework(int x, int y): Constructor to initialize the launch position.void launch(): Simulates the ascent of the firework and triggers the explosion.- Calls
printFrameto show the firework moving upwards. - Pauses for a short duration between frames using
std::this_thread::sleep_for. - Calls
explodewhen the ascent is completed.
- Calls
void explode(): Simulates the explosion effect by creating a visual effect of expanding stars.- Calls
printExplosionFrameto show the expanding effect. - Pauses between frames for the explosion effect.
- Calls
- Private Methods:
void printFrame(int x, int y) const: Clears the console and prints the firework’s position.- Uses
system("clear")for Linux/Mac orsystem("cls")for Windows (comment/uncomment based on OS).
- Uses
void printExplosionFrame(int x, int y, int radius) const: Prints the explosion effect by expanding the radius of stars.- Clears the console and prints stars in a radius pattern.
- Private Members:
mainFunction:- Prompts the user for the firework’s launch position.
- Creates a
Fireworkobject with the specified position. - Calls
launchto simulate the firework’s ascent and explosion.
