How to write dynamic fireworks in C language: first draw the menu interface to display text; then set the rising stage and explosion stage of the fireworks, define the fireworks and fireworks bomb structures; finally initialize the data, load the resource map, and launch randomly The number is random.

Fireworks: coordinate position, explosion radius, maximum radius, distance from the center to the upper left corner, length and width, pixels, time, etc.
Fireworks: coordinate position, highest point, whether to launch, time, number, etc.
Initialization data. Load resource maps. The number of random launches is random,
