Thread: Processing Arrays

I have an int array called oddNumbers: int [] oddNumbers = {1,3,5,7,9}

I want to process oddNumbers in the following way;

For each element of oddNumbers (except the last element at index 4 i.e 9 ) to copy into that element
the value from the element to its immediate right.

This means that the value in index 1 (i.e 3) is copied into index 0, the value in index 2 is
copied into index 1 and so on, until the element at index 4 is copied into index 3.
The contents of the rightmost index 4 (i.e 9) will remain unaffected.

After processing the array oddNumbers, it should have this appearance: int [] oddNumbers = {3,5,7,9,9}

I would be grateful for some help in coding to achieve this.

Best wishes

For this kind of problem, take a piece of paper and a pencil. Draw the array with the numbers.
Put a pointer under the source element, note the position/index.
Put a pointer under the target element, note its position.
Move the element at the source to the target by erasing the target value and writing in a copy of the source element.
Change the values of the indexes to do the next step.

Now look at how you had to change the index values to get to the next step.
That will tell you how to write a program to do this.

After you get the idea of how to move the index, have you tried writing the code?
