Как использовать массивы строк и/или символов в классах...

---

I am writing a very simple c++ program to print the name of the sender, recepient and time of an  email message using classes. It shows the following errors. I am having difficulty using string and/or char arrays in classes. However, if I use single char, it does not show error. Please help me out.

Что я уже пробовал:

#include<stdio.h>
#include<conio.h>
#include<iostream.h>
#include<stdlib.h>
class message
{
private:
char sender[10];
char recipient[10];
int time;
public:
message (char s[10],char r[10],int t);
void print();
};
message::message (char s[10],char r[10],int t) 
{
sender=s;//  ERROR lvalue required
recipient=r;    // ERROR lvalue required
time=t;
} // ERROR parameter s and r are never used
void message::print()
{
cout<<"the sender is:  "<<sender;
cout<<"the recipient is : "<<recipient;
cout<<"current time is : "<<time;
}
main()
{
char s[10], r[10];
int t;
clrscr();
cout<<"enter senders name :";
cin>>s;
cout<<"enter recipient name :";
cin>>r;
cout<<"enter current time :";
cin>>t;
message c(s,r,t);
c.print();
getch();
}
