C。。新手C++问题。。求大神。。
#include<iostream>
using namespace std;
class cuboid
{
public:
void cuboid_input();
public:
double lenth;
double width;
double height;
double volumes;
};
void cuboid::cuboid_input()
{
cout<<"lenth:";
cin>>lenth;
cout<<"width:";
cin>>width;
cout<<"height:";
cin>>height;
}
int main()
{
cuboid volume;
  volume.cuboid_intput();/*error C2039: 'cuboid_intput' : is not a member of 'cuboid......是怎么回事啊？*/
return 0;
}


------解决方案--------------------
cuboid_input()与cuboid_intput();自己看看
------解决方案--------------------
细心点啊

cuboid_intput ==> cuboid_input
