I am working on a C++ program. I saw multiple lines of logs in this pattern in one of the files:

#include <iostream>

using namespace std;

int main()
{
    std::cout << "First line"
                                                " second line" << std::endl; 

    return 0;
}

I am not very familiar with cpp language, is this a standard way of logging and how does it work? I feel like it should give some kind of syntax error on a quick look?

Normally you'd just put another `<<` at the beginning of the second line to make things clearer and more readable. – Retired Ninja May 11 '22 at 08:12

To log a simple string in C++ one can type std::cout << "My String.";

To log a variable one can replace "My String" from before with their variable.

to either add a string or another variable to a std::cout one can add "+ "My String"" or + MyVariable.

To end a line and begin writing to the line below one can add \n to their string.

To play a sound one can add \a to their string.
