Hi! Are you searching for how to write a C++ hello world program? I hope I will be able to help you with that.
Hello world C++ program
#include <iostream> // Declaration of header
using namespace std; // Using std namespace
int main() // Function main through which program execution begins
{
cout << "Hello World"; // Displaying "hello world"
return 0; // Returning 0 indicates success to the operating system
}
C++ hello world program using a class
#include<iostream>
using namespace std;
// Creating class
class Message
{
public:
void display() {
cout << "Hello World";
}
};
int main()
{
Message t; // Creating an object
t.display(); // Calling function
return 0;
}
