The pass is passed under TC 3.0, because TC 3.0 does not support the Bool type, so a modified type variable Bool is defined in the program If you run in the VC or BC, you can take this BOOL type. Core algorithm for the snake How to achieve mobile and eaten food. When you encounter food, enter the next node in the current movement direction, and redraw this node with the color of the snake node. Then take the node refers to the nodes referred to, and The game frame inside the background color is redrawged from the team's node, so that the movement can be achieved. When you eat food, just enter the team .// Greedsnake.cpp # include
