Hi there!
Been using the Questions Section over at Udemy to show off the work I’ve done along the course and will be using this thread in order to keep a record on the stuff I do. Feedback will be gladly appreciated, and thank you for stopping by :raised_hands:

Currently on Section 3: Coding the basic Game Loop

This is what my code looks like:

BullCowCartridge.h 
#include "BullCowCartridge.h"

void UBullCowCartridge::BeginPlay() // When the game starts
{
Super::BeginPlay();
    PrintLine(TEXT("Welcome to the Bulls & Cows guessing game!"));
    PrintLine(TEXT("Press TAB to access the terminal."));
    PrintLine(TEXT("Guess the word and press ENTER to see if you were right!"));

}

void UBullCowCartridge::OnInput(const FString& Input) // When the player hits enter
{
    ClearScreen();
    FString HiddenWord = TEXT("Tongue");
    PrintLine(Input);
    if (Input == HiddenWord)
    {
        PrintLine(TEXT("You got the word!"));
    }
    else
    {
        PrintLine(TEXT("Wrong word!"));
    }
}

As said in the course video, we are initializing the code each time we press enter, so we need to move it to BeginPlay() or store it somewhere else so we can change it after playing the game, and also needs to be readable inside the OnInput() function.

Early Returns Code Refactor Assignment:
Only change I would make is I’d move the Lenght check before the isogram one. So we only punish when they get an isogram but it’s not the one we are looking for (which the code was already doing, but I prefer checking if the length is wrong first so we can stop the flow of the code sooner).

Took a break!
Back to it with “for loops”.

Summary 
bool UBullCowCartridge::IsIsogram(FString Word) const
{
    
    for (int32 i=0; i<=Word.Len();i++)
    {
        PrintLine(TEXT("%c"), Word[i]);
    }

    for (int32 i = 0; i <= HiddenWord.Len(); i++)
    {
        PrintLine(TEXT("%c"), HiddenWord[i]);
    }
    //get first char of HiddenWord
    //check first char against the other ones until the length of word
    //if char is equal to other one
    // return false;
    //
    //else return true;
    return true;
