Who have c++ program that include string,pointer and 2D array?

Here you go. This program meets all your requirements:

#include <iostream>
int main()
{
char name[1][80];
std:: cout << "What is your name?" << std::endl;
std::cin >> name[0];
std::cout << "Hello, " << *name << std::endl;
}

It uses a string, a 2D array and there is even a pointer hidden in there.

I don't like the question, I can't see any natural commonality in it. I
would be inclined to write three little programs and just cobble them
together with main having something like

demo1();
demo2();
demo3();

The hardest one is the 2D array. You could look at old Usenet messages or
the FAQ for C for help. I would start with the FAQ.

No. Who's on first.

However, I'm in a good mood. Tell you what I'll do.
Just post your instructor's email address here, and I'll
write up the program, and just send it to him directly,
and save you the trouble.

Also, you might find a good program here:

Post what you have and ask for specific help.
