问题2. 什么时候执行构造函数和析构函数 22:59:40 2015-07-22
做了一个实验：
#include <iostream>
class Object{
public:
Object(){
printf("Create Object\n");
};
~Object(){
printf("Delete Object\n");
}
};
void runObject(){
Object obj;
printf("runObject end\n");
}
int main(){
// Object *obj=new Object();
// delete obj;
runObject();
printf("end\n");
return 0;
}
输出为：
Create Object
runObject end
Delete Object
end
在void runObject()中加一个{}
#include <iostream>
class Object{
public:
Object(){
printf("Create Object\n");
};
~Object(){
printf("Delete Object\n");
}
};
void runObject(){
{
Object obj;
}
printf("runObject end\n");
}
int main(){
// Object *obj=new Object();
// delete obj;
runObject();
printf("end\n");
return 0;
}
输出为：
Create Object
Delete Object
runObject end
end
