Say "Hello, World!" With C++ hackerrank solution

      
    #include <iostream>

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

Let's go through the code and explain each part:

#include : This is a preprocessor directive that includes the necessary input/output stream library for C++.

int main(): This is the main function of the program. It is the entry point for execution.

std::cout: cout is an output stream object from the iostream library that represents the standard output (usually the console). We use std::cout to display output to the console.

"Hello, World!": This is the string we want to print.

<<: The << operator is used to insert the string into the output stream.

std::endl: endl is used to insert a new line character into the output stream. It is equivalent to \n.

return 0;: This line indicates that the program execution is successful and returns the value 0 to the operating system.

When you run this program, it will output "Hello, World!" to the console.

To use this code in HackerRank, you can copy and paste it into the editor and submit it. The output will be displayed in the output window or terminal, depending on the HackerRank environment.

Remember to include the necessary header files (#include ) and use the correct function signature (int main()) as shown in the example above.
