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.
Dynamic graph

First draw the menu interface to display the text. Fireworks have a rising stage and an explosion stage, which define the structure of fireworks and fireworks bombs.
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,

The two pictures are placed under the fire folder. As for music, just find a piece of music and put it in, and then it can be played.
Summary
You need to install the graphics library and understand the relevant knowledge. The material path must be written correctly, otherwise it will have no effect.
