Console.WriteLine(string.Join(", ", oystersEaten));

it runs fine up until p.bubbleSort i think, im not sure how to call my function properly im just trying to use the sort to sort the array

What's p? Your bubbleSort() takes an array of integers You call it on some p object without giving it any data

Jimmacle•4mo ago

yeah this code won't even compile, let alone run you'd call your function like bubbleSort(array);, because it's not a member of p (p doesn't exist at all?) you can't do p.bubbleSort(); there is a way to use that syntax called extension methods, but that's not what you have here

i just removed the p and it worked

Console.WriteLine($int.Parse(count3),". {cnames[count2]} ate {oystersEaten[count2]} oysters");

Console.WriteLine($int.Parse(count3),". {cnames[count2]} ate {oystersEaten[count2]} oysters");

but im trying to output an integer at the start of the write line and its saying it cant be parsed or smth

Angius•4mo ago

This will not compile

js•4mo ago

yh ik its not idk what im doing wrong

Angius•4mo ago

Console.WriteLine() with more than one parameters expects the first one to be a template string And the rest to be data to insert into the template Use $interpolation

MODiX•4mo ago

String interpolation is the preferred way of building strings in C#. It is easier to read than concatenation. For example:

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

can be written as:

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");

it was working fine till i added the int parse count 3 bit

Angius•4mo ago

Well, you added it outside of the string Where the template string goes So "I hit my TV with a hammer to switch the channel and it no longer works" vibes

Jimmacle•4mo ago

either a) it did not work or b) you did more than just remove the p please be specific instead of saying "not work," there are a lot of possible problems from compile time errors (your program will not build and you have red squiggles) to run time errors (the program doesn't do what you want or it crashes)

js•4mo ago

cs    
File.AppendAllText(filepath, $"{count3}. {cnames[count2]} ate {oystersEaten[count2]} oysters");

cs    
File.AppendAllText(filepath, $"{count3}. {cnames[count2]} ate {oystersEaten[count2]} oysters");

this line is running in a loop but each loop it isnt outputting to a new line its just adding to the end how do i go onto a new line after every iteration

Angius•4mo ago

Add a newline character, for example \n Or see if maybe there is File.AppendLine() method
