how to print text on C++

To print text in C++, you can use the cout object from the iostream library. Here's how you can do it, step by step:

  1. Include the necessary header file:
#include <iostream>

This line includes the iostream header file, which contains the definition of cout and other related objects.

  1. Use the cout object to print the text:
std::cout << "Hello, World!";

This line uses the << operator to send the text "Hello, World!" to cout, which represents the standard output stream. The std:: prefix is used to specify that cout is part of the std namespace.

  1. End the line (optional):
std::cout << "Hello, World!" << std::endl;

You can use << std::endl to end the line and move the cursor to the next line. This is optional, but it's commonly used to print each output on a new line.

  1. Compile and run the program: Save the file with a .cpp extension, such as main.cpp. Then, compile and run the program using a C++ compiler.

Here's the complete code example:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

This code includes the iostream header file, defines the main function, and uses cout to print the text "Hello, World!" followed by a new line.

When you run the program, you should see the output "Hello, World!" printed on the console.
