C ++-implemented console-snake and Snake

C ++-implemented console-snake and Snake

Saturday can finally be used for a whole period of time.

If you want to write a snake, the first time you write about 140 lines is not too much.

In the future, ACM won't be able to compete.

Ps: I wanted to write a project, but I wrote it in a file for your convenience.

No major bugs tested, but no tests are successful.

 

 

Knowledge point:

1: refresh the window system ("cls ");

2: time. h is used to compile the clock system;

3: SetConsoleCursorPosition (GetStdHandle (STD_OUTPUT_HANDLE), coord); reset the cursor position, that is, if you want to output it there, move the cursor to that place and output it.

At first, another idea was to update the rear of the snake by just locating the cursor without storing arrays and maps.

4: others are some basic C ++ syntaxes.

You can take it for fun.

Code:
