기본을 반환하는 C++ 프로그램

Question

기본적으로 사각형 클래스 인 초급 C++ 프로그램을 작성했습니다. 프로그램이 잘 컴파일, 내가 가지고있는 유일한 문제는 너비에 대한 제로를 반환하고 나는 이유를 파악할 수 없다는 것입니다. 나는 누군가가 나에게 잘못 가고 나를 도와 줄 수 있는지 정말로 고맙게 생각합니다.

Answer 1

귀하의 setWidth 기능은 실제로 0으로 width 멤버 세트를 떠나, 당신의 height 멤버 변수를 설정하는 것입니다 :

//set width function 
void theRectangle::Set_Width(int _width) 
{ 
    height = _width; 
} 

그것은해야한다 :

이

//set width function 
void theRectangle::Set_Width(int _width) 
{ 
    width = _width; 
}
