프로그램을 실행하면 평균이 나오지만 루프가 발생하지 않습니다! 아무도 내가 뭘 잘못 확인하고 while() 루프 후 세미콜론이 올바른 방향루프가 작동하지 않습니다.

어떻게'calcAverage'에'calcAverage (double & score1, double & score2, double & score3);와 같은 세 개의 매개 변수를 원하지만'calcAverage (avg);와 같은 하나의 매개 변수를 제공합니까? 나는 C++ 소년이 아니다. 내가 물어 보는 것이 멍청한 놈이라면. 나는 또한 당신이''while (avg! = - 1)''을 제거해야한다고 생각한다. (avg! = -1) : – Bastardo
