The following code :
===========================

#include<iostream.h>

cout<<"Input Id : ";cin>>id;
cout<<"Input Name : ";cin.clear();cin.seekg(0,ios::end);cin.get(name,20);
cout<<"Input Amount : ";cin>>amount;
}
void output(){
cout<<id<<"\t"<<name<<"\t"<<amount<<endl;
}

}

else if(amount<=m) amount=0;

}
};

}
