这段代码
总是编译不过去但自己不会改了
高手能否帮我看看帮我改好并说明一下谢谢了

PS：我只是想把它给编译通过只要不报错就行
#include
#include
class Shape {
public:
Shape() {}
~Shape() {}
void setArea(double a) {area = a;}
private:

double area;
};

class Circle: public Shape {

Circle() { texture = malloc(TEXTURE_SIZE); }

~Circle() { free(texture); }

bool operator!=(Circle &r);

private:

TEXTURE_DATA *texture;

Circle(Circle &r) { texture = strdup(r.texture); }

Circle& operator=(Circle &r) { if (r != *this) texture = strdup(r.texture); return *this;}

};

void foo() {

Shape *newObj = new Circle;

delete newObj;

}
int main()
{

return 0;
}

出去TEXTURE_DATA的问题。在Circle() { texture = malloc(TEXTURE_SIZE); }~Circle() { free(texture); } 之前加上publicShape *newObj = new Circle; 最好改成Shape *newObj = new Circle();...

Shape *newObj = new Circle();...
