하강 매트릭스 구현
컴퓨터가 등장한 이후 헐리우드에서는 해커나 프로그래머를 컴퓨터에 앉아 컴퓨터에 임의의 키를 입력하는 누군가가 궁극적으로 시뮬레이션과 같은 낙하 매트릭스로 컴파일되는 모습을 크게 보여주었습니다. 여기서는 C++를 사용하여 콘솔에서 유사한 하강 행렬 시뮬레이션을 구현해 보겠습니다.
여기서 아이디어는 두 개의 연속 문자가 무작위로 정의된 특정 양의 간격을 가질 수도 있고 그렇지 않을 수도 있는 정의된 너비에 걸쳐 임의의 문자를 인쇄하는 것입니다. '하강 효과'를 가지려면 연속적인 라인을 인쇄하는 사이에 일정량의 지연을 구현해야 합니다.
