Using Out parameter

I might be dumb but I can't wrap my head around the Out parameter in self defined methods. Is Out used to create a boolean value? When do I call upon it and why? I was cruising through the course but I just don't understand this parameter, while I think it's probably not even that difficult. :P I asked ChatGPT to explain it to me like I'm 12 and I still didn't get it! Just made it work after a lot of trial and error in CodeAcademy but honestly barely knew what I was doing with it and why. See code for reference! Can someone maybe help me grasp it a bit better? :)

Just noticed that my code didn't even apply the method that I've created, here is the corrected version for reference. :

you printed the string not the out var

Compile C# code in #bot-spam, use !eval Example:

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

        }
        
        Console.WriteLine("result is : " + TestOut(2, out var nombre) + "  number is : " + nombre);

bool TestOut(int input, out int numba)
        {
            numba = input;
            return input > 1;    
        }
        
        Console.WriteLine("result is : " + TestOut(2, out var nombre) + "  number is : " + nombre);

Console Output

result is : True  number is : 2

result is : True  number is : 2
