I have found a strange answer to one of the exercises.

Here is the exercise: https://www.codecademy.com/courses/learn-c-sharp/lessons/csharp-working-with-text/exercises/get-parts-of-strings

The way we are taught and expected to answer goes along those lines:

      int charPosition = name.IndexOf("F");
      char firstLetter = name[charPosition];

Isn’t it strange? We write a code for finding what the first letter is by writing the first letter manually. Wouldn’t a better answer be:

char firstLetter = name[0];

I am no pedagogy specialist, but I would tend to believe that the intend answer is a bit redundant and purposeless. What do you guys think?

P.-S.: I’m a new C# learner, so maybe I got something completely wrong. Let me know if I did.


I agree with you that if all we’re trying to do is get the first letter of a string, and convert it char
char firstLetter = name[0]; is much more efficient. Probably, they were trying to illustrate the use of the IndexOf() method, but it might have been a better lesson if they used a letter other than the first, and named the variable something like positionOfLetter.
Maybe something like this would demonstrate the functionality of IndexOf() better:

string name = "Benjamin Franklin";
int charPosition = name.IndexOf("F");
char firstLetter = name[charPosition];
Console.WriteLine(firstLetter + " is the " + charPosition + "th letter in " + name + ".");

Actually it would be the charPosition + 1 letter since IndexOf() starts at 0. Oops! :man_facepalming:

Console.WriteLine(firstLetter + " is the " + (charPosition + 1) + "th letter in " + name + ".");

Upvoting. Hopefully they revisit this lesson refactor.


I completely agree! I couldn’t even figure out what I was supposed to use for IndexOf(), because each person will have a different letter.


Agreed. This entire lesson needs to be reworked. It’s not practical, efficient, or realistic. Also, overall, I hate how the lessons require you to declare variables specifically using int, string, bool, etc instead of using var. Let C# do the work of figuring out what’s what.


I agree that this lesson needs to be reworked. I did not find the instructions clear on what exactly was I supposed to do. The coding itself is pretty easy.


IMO, I don’t recommend letting C# do an extra job, if you know the type of variable, why let C# store any type? that is a bad practice, you don’t have control what you want store/receive/send and the code will be hard to read and follow if you throw any error.

Agreed with this. char firstLetter = name[0]; is not just more efficient, but it’s better design. It makes the function usable for more than one hard-coded name.

Codecademy, please consider reworking this lesson.

How about the last part of the exercise?

This is what I tried,

// Print results Console.WriteLine(firstLetter.ToString() + ' ' + lastName);

and this was the result.


Had to change it to this to get the result I would have expected to be the correct answer:

Console.WriteLine(firstLetter.ToString()+ ' ' + lastName);

Also agree. I was lost because I was trying to make it find the first letter of any input, and never even considered this was the only name to use. Why would I? Some of these lessons make learning way harder than it should be

I agree it appears the to me that they want us to do something like.

int firstChar = name.IndexOf(“F”);
char firstLetter = name [firstChar];

But in real world case you may not know the persons name so some thing like.

int firstChar = name.IndexOf[0];

might be more use full . Dont get me wrong I am just learning an am by no means an expert, so my code is probably flawed but hope you get the point.

Hello, @tera5049690011.

I think the exercise intended to teach finding a character in a string, and retrieving its index. Using the first character in the string was not the best way to do it. I agree with your sentiment, but your real world case has a small error:

Thanks midlindner for lettinng me know
