I wish this helpful for you If you simply want to remove all the negative elements in the Array you can do:
arr = Arrays.stream(arr).filter(e -> e >= 0).toArray();

it fixes the issue If an element in the array is less than zero, multiply it by -1. Don't turn it into an unsigned number, that's probably not going to do what you think it does. Also, as mentioned, what you are doing in your code snippet isn't even modifying the element in the array, it's trying to declare a new array. So basically you should do:
if arr[element] < 0 {
    arr[element] *= -1;
}

How to remove an element in a character array or create a copy of a new array without specific elements?

Any of those help Rather than trying to update the string you have, just print out a character if it's a letter.
Also, upper case and lower case characters don't immediately follow one another, so you need to check for them separately:
printf(" Your new message is: ");
for(int i = 0; i< strlen(my_array);i++)
{
    if((my_array[i] >= 'A' && my_array[i] <= 'Z') || 
       (my_array[i] >= 'z' && my_array[i] <= 'z'))
    {
       putchar(my_array[i]);
    }
}
printf("\n");
if (isalpha(my_array[i]))

Copy the last element of an array into a different position, and then remove it from the end of the array

Any of those help I'm looking for a neat (single-statement) method for copying the last element of an array into a different position (overriding an existing element), and then removing it from the end of the array. , You can try this:
function func(array, index) {
    array[index] = array.pop();
    return array;
}

// Or
// const func = (array, index) => (array[index] = array.pop(), array);

const arr = func([1,2,3,4], 1);

console.log(arr);
function func(array, index) {
    if(index < array.length -1) array[index] = array.pop()
    else array.pop();
    return array;
}

// Or
// const func = (array, index) => (index < array.length -1 ? array[index] = array.pop() : array.pop(), array);

console.log(func([1,2,3,4], 1));

console.log(func([1,2,3,4], 3));
