Ubuntu – C++ console output not switching to a new line when the program ends

So I’m just starting to learn C++, and I’m just trying to get everything set up. When I run the compiled binary for my hello world code, it display’s the console output, but doesn’t switch to a new line afterwards. Here’s an example:

Hello, World!michaela@michaela-HP-Laptop-17-by4xxx: $

I tried researching, but I can’t find a good solution. I’m on Ubuntu 20.04, and using the BASH shell. I will provide the code if it’s any help, though I doubt it as it literally just outputs "Hello, World!".

#include <iostream>

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

    try this :

    std::cout << "Hello, World!"<<std::endl;

    or you can use this one :

    std::cout << "Hello, World!n";

    The only difference between std::endl and n is that std::endl adds std::flush (to flush the output stream), which is usually totally unnecessary and makes the program slower.

    This is completely normal for the majority of programming languages, especially in a Unix environment. Even shell scripting will print without a newline if you use printf or echo -n. And thanks to the terminal emulating an old teletype-like printer-based system the cursor won’t reset just because a program exitted.

    If you want a newline add a 'n' to your string or output a std::endl after your text.
