Question

Create a Chat class: A chat is a message consisting of 140 characters or less. It also has an author and a time stamp.

Write a main program that nicely demonstrates the usage of your class. Hard code a vector of 3 chats. no user input

can you please make sure to add the time stamp similar to a text message output

//chat.h

#pragma once

#include<iostream>

#include<string.h>

#include<ctime>

using namespace std;

class chat

{

char message[140];

char author[20];

char current_time[40];

public:

void setMessage(char *msg);

void setAuthor(char *s);

void display_message();

chat(string au, string message);

};

char buf[80];
