설계독학맛비's 실전 Verilog HDL Season 1 (Clock부터 Internal Memory까지)

안녕하세요 맛비님. 유튜브랑 강의 잘 챙겨보고 있는 비메모리 설계 꿈나무 4학년 학생 입니다. 조금 주제를 벗어난 질문 일지 모르지만 강의나 유튜브에서도 가끔 언급을 하시는 C 언어 실력 관련한 질문입니다 ㅎㅎ;; 현재 저는 C++ 문법정도만 유튜브 강의를 통해 학습한 상태인데, 맛비님이 설계를 잘 하기 위해서는 C 도 필수로 하셔야 한다고 해서 걱정이 됩니다. C로 뭘 만들어본 경험이 하나도 없어서요 .. 시간이 있어서 미리 공부를 차근차근 해놓으려고 하는데, 이 상황에서 어떤 방향성을 가지고 공부하면 좋을까요?(베릴로그는 따로 공부중입니다.) 간단하게 라도 조언 해주시면 큰 도움이 될 것 같습니다 !! 예를들어 백준 알고리즘 문제를 풀어봐라, 어떤 종류의 강의를 한번 들어봐라 이런식으로 라도 짧게 대답해주셔도 됩니다!!
