What's going on

This C++ program stores a name in a string and prints it with cout. Same skeleton as Hello World, plus a variable.

#include <iostream>

Needed for cout.

#include <string>

Needed for string. Some compilers pull it in through iostream. Others don't. Include it, or this file builds on one machine and dies on another.

using namespace std;

So string and cout don't need std::.

string name = "John Doe";

A variable holding text. = copies the literal in. Change the quotes, the output changes. This is not cin yet — the name is baked into the source.

cout << "My name is: " << name << endl;

Chain <<. First the label, then the variable, then endl (newline + flush). Forget endl and the next prompt glues onto this line.

Sample: name is "John Doe" → My name is: John Doe.

A C string char name[] = "John Doe"; also prints. string is the one you want for later input and concatenation.

Hard-coding the name is the demo. User Input is the version that reads it with cin.
