Create a function that will animate a Flomb - all the arms change: \ -> / and / -> \ in each frame

i.e.
\(O_O)/ -> /(O_O)\

Let's say a rough parameter for the function is (C++)

void animateFlomb(const string& flomb, int numberOfFrames);

if animateFlomb("\(O__O\)",5) was called:
The output would be
\(O__O\)
/(O__O/)
\(O__O\)
/(O__O/)
\(O__O\)

Another function to create:

string flipHorizontalFlomb(const string& flomb)

This will flip a Flomb, but it's not a case of reversing the string because if:

\(O__O\) was reversed it would look like: )\O__O(\ which doesn't look right
Instead of flipping it like that, the function should flip it like:

\(O__O\) -> (/O__O)/

Then create a flipVerticalFlomb(const string& flomb)

\(O__O\) -> /(O__O/)
(flips the arms)

Using the basic ideas in the functions created

Make a function

void danceFlomb(const string& flomb, int numFrames)

That will flip the Flomb horizontally then vertically then horizontal... etc until the numFrames counter is reached
i.e.

danceFlomb("\(O__O\)",6) would output:
\(O__O\)
(/O__O)/
(\O__O)\
/(O__O/)
\(O__O\)
(/O__O)/
(repeats every 4 frames)

Also play around with clear screen commands (i.e. Windows only system("cls")) and wait commands to make an animation instead of a list of frames, and colouring the console (i.e. Windows: system("color AA") etc) so you could make a dance animation with lots of colours Smile
