程序代码：

#include<iostream>
#include<cstring>
struct candbar{
    int d;
    char name[20];
    float heavy;
};
int main(){
    using namespace std;
    candbar *snak=new candbar;
    cin>>snak->d;
    cin.getline(snak->name,20);
    cin>>snak->heavy;
    cout<<snak->d<<endl<<snak->name<<endl<<snak->heavy;
    return 0;
}
