#removes adjacent duplicate in an Array

I would love some advice on how to get this to work. Is it possible to remove an element from an array?
quartz lagoon
are you trying to make the program efficient or are you trying to get it done quickly
if you're going for efficiency you shouldn't use strcmp, you should use a hash function
rugged blade
I'm going to keep strcmp but i want to know if it's possible to remove an element from an array?
quartz lagoon
yes it is
rugged blade
And what function or method does that?
quartz lagoon
you should create the function yourself. what you're going to need to do is assign the ith elment of the array to the value of the last element of the array, then use realloc() to reallocate the array to one element of size smaller
rugged blade
realloc() is not something we have gone through on the course. Is there any other method?
grim robin
strcmp in this case won't work, as you are trying to compare characters and not strings, you have to just use a normal comparison
grim robin
yes

I had gpt help me
// 2023 Alexander Johansson
#include <stdio.h>
#include <string.h>
int main()
{
char array[60];
while (scanf("%59s", array) == 1)
{
int len = strlen(array);
for (int i = 0; i < len - 1; i++)
{
if (array[i] == array[i + 1])
{
for (int j = i + 1; j < len; j++)
{
array[j] = array[j + 1];
}
len--;
i--;
}
}
printf("%s\n", array);
}
}
I'm just a little confused on what the last for loop does
for (int j = i + 1; j < len; j++)
{
array[j] = array[j + 1];
}
that should work
quartz lagoon
I'm just a little confused on what the last for loop does
```c
for (int j = i + ...
the last for loop goes through the array from the current index setting every element to the elemtn in front of it

you can visualize removing an element from an array as looping over the elements to it's right and copying them by 1 to the left
[51] [53] [12] [74] [10]
XX
[51] [12] [74] [10] [10]
you just have to implement such thing by yourself, but we can of course help if you feel stuck
(of course you'll need to handle the last element being there twice, but you can decide for yourself how to do such thing)

So if the word that is put in is e.g. Programming
quartz lagoon
then programing
quartz lagoon
yes
grim robin
yeah
rugged blade
But what happens with the final 2 dublicate g:s?
rugged blade
Programming
Yes if i have this, at the end i will have dublicates g:s
quartz lagoon
no you won't
why would you have duplicate g's
the g is assigned to the null terminator
after the n is assigned to the g
grim robin
But what happens with the final 2 dublicate g:s?
you can decide yourself what to do in that situation, but because you are dealing with a string you probably want to set the last elemento to 0, the string terminator
rugged blade
Ah yeah i see
rugged blade

you know that's funny cause it looks like not solved
