Step 1: Divide the decimal number that you want to convert by the value of the desired base.

Step 2: Use the remainder from step 1 as the rightmost digit, aka the least significant digit, for the new base number.

Step 3: Replace the original decimal (base 10) number with the quotient from the first step.

Step 4: Repeat step 1-3 until the quotient in step 3 is zero.

Note: The remainder you get at each step will become part of the new base number. The new base number is obtained by putting the remainders in reverse order.

In terms of our breakout, in which our brick structures are stored within our singly-linked list. When a brick is destroyed, it's likely that you're simply turning the visible flag to false. Once a brick is invisible, it still exists in memory even if nothing interacts with it. Freeing that brick from memory will improve performance, especially if you have a triple digit amount of bricks.

In our singly-linked list, we have two pointers: one at the start of the list and one at our current position in the list. Due to the limitations of the structure, we're unable to delete the node we're currently have selected with the current pointer. We're only able to delete the node before or after the one currently selected. In this example, we'll delete the one after.

To start, create a new brick struct pointer. We'll call it temp. Next, you'll want to assign temp to point at the node after the one currently selected by making use of current→next.

.wav files can be included into your programs to produce sound.

The first thing you will want to do is to include the .wav file in your Make.sh. To do that nano into your make.sh and add the following:

echo
echo Convert the WAV sounds
echo
wav2vircon Paddle-ball.wav -o Paddle-ball.vsnd || abort_build
wav2vircon Brick-ball.wav -o Brick-ball.vsnd || abort_build
wav2vircon Miss-ball.wav -o Miss-ball.vsnd || abort_build

Depending on the number of .wav files you have, you may have more or less instances where you are calling wav2vircon.

You will also want to include it in your .xml file. Start by nanoing into your .xml file. Once your .xml file is open, add the following:

    <sounds>
        <sound path="Paddle-ball.vsnd"/>
        <sound path="Brick-ball.vsnd"/>
        <sound path="Miss-ball.vsnd"/>
    </sounds>

It is important that the file ends with .vsnd and not .wav. the .vsnd file is created by the make.sh file.

Then in your program you will want to include the audtio.h library and define the sound.

    #include "audio.h"
    #define your_sound number

To use sound in your program you will want to reference the audio.h library using the C API reference http://www.vircon32.com/api.html or you could also look at the shooterGameVideo .c file in github. Here is the link: https://github.com/vircon32/ConsoleSoftware/blob/main/Tutorials/ShooterGameVideo/Tutorial-Shooter.c

Adding sound to your game is actually extremely simple, where ever you want to use one of your sound files simply add the following line and specify which sound you want:

    play_sound( your_sound );

If you are running into an issue where the audio is overlapping creating a staticy noise, a good idea is to set the sound that you want to play to a channel. Then use the play_channel(channel number, your_sound) function, which causes the target channel to start playing its given sound if it is stopped or paused. It will also restart playback on a paused channel. If the channel is currently playing, it will retrigger the original sound. For certain games, this may be a better situation as the sound never triggers in tandem.

  assign_channel_sound(channel_number, sound);
  play_channel(channel_number)

If however you want the whole sound to play out without repeating itself in the middle, there is another way. the get_channel_state function gets the state of the channel you input as its perameters.

  if(get_channel_state(0)!=channel_playing){
    play_channel(brick_b);
  }
