❔ Homework Help. Make every element in char array alternate between upper and lowercase: LiKeThIs

I am working on an assignment where I am given a char[] words, and must convert it so that the characters in the array alternate between upper and lowercase. Any help on where to start?

Little update, I ran the program to check the random inputs a few times and it looks like all the inputs are fully uppercase, so I will just need to convert ever other index to lower. Seems that even indexes are upper and dd indexes should be lower.

Hi So if the word is "good" You'd need it as G,o,O,d ?

kyoOP•3y ago

yes

Shinigami•3y ago

You could loop over the char array and divide every index number by 2

kyoOP•3y ago

 public static void Test10(char[] word)
        {
            for(int i = 0 ; i < word.Length; i++)
            {
                if(i % 2 == 0)
                {
                    
                }
            }
        }

 public static void Test10(char[] word)
        {
            for(int i = 0 ; i < word.Length; i++)
            {
                if(i % 2 == 0)
                {
                    
                }
            }
        }

this is what i have so far

Shinigami•3y ago

You need to add condition for when index is 0 as well

kyoOP•3y ago

|| i == 0 ?

Shinigami•3y ago

If index = 0 then upper Yeah

kyoOP•3y ago

okay so then I would just convert the even indexes to lower lemme check if expected outputs want 0 as upper or lower

Shinigami•3y ago

Sure

kyoOP•3y ago

okay i read it wrong, even indexes are upper, odd indexes are lower. so maybe i could do

i % 2 != 0

i % 2 != 0

to check that they are not even and then do ToLower?

Shinigami•3y ago

Yes If i % 2 is anything else than 0 then it it's odd

kyoOP•3y ago

okay so what would the proper syntax for tolower in this situation? i tried

.ToLower(word[i]);

.ToLower(word[i]);

no clue

Shinigami•3y ago

Do one thing Make the word into a char array Like this

kyoOP•3y ago

it starts as a char array

Shinigami•3y ago

Oh sry, then it's easy. This should work 1 sec

kyoOP•3y ago

this is the error im pulling

Shinigami•3y ago

Just do this Word[i].tolower()

kyoOP•3y ago

ok no overload method, takes 0 srgs args*

Shinigami•3y ago

?? Can you show the error

kyoOP•3y ago

Shinigami•3y ago

Oh i guess since it's already lowercase it's throwing that error

Refer this

kyoOP•3y ago

would i have to do like i => 'A' && i <= 'Z' oh okay thank you i will look at that

Angius•3y ago

It's char.ToLower('A') not 'A'.ToLower()

Shinigami•3y ago

Bingo, sry this is the way to go @apparition

fun homework you got there.. just answering for fun

kyoOP•3y ago

your answer is great, unfortunately, we arent allowed to use var

Angius•3y ago

Just use the actual type, then var is not magic

string foo = "hello";

string foo = "hello";

and

var foo = "hello";

var foo = "hello";

are the exact same
