One of my students introduced a class to FizzBuzz (via Python - where this is apparently a "thing").

Anyway, the "challenge" is to code something in MMBasic (via CMM2 for us) that prints the numbers from 1 to 100 and replaces the number with Fizz for multiples of 3 and Buzz for multiples of 5. 15 will therefore get FizzBuzz as it is both.

Currently this is my example code:

For i = 1 To 100
T= i Mod 3
F = i Mod 5
If T = 0 Then Print "Fizz";
If F = 0 Then Print "Buzz";
If T<>0 And F<>0 Then Print I;
Print
Next i

Any variants? Can it be simpler (ie less code, less If statements)? My class have been challenged to drop few my way this week..

Student #1

For i = 1 To 100
s$=""
If i Mod 3 = 0 Then s$ = s$ + "Fizz"
If i Mod 5 = 0 Then s$ = s$ + "Buzz"
If Len(s$) > 0 Then
Print s$
Else
Print i
End If
Next i

Different - but still 3 IFs (actually and else - so does that count as 4?)

Student #2 (am sure this is via the Internet..)

dim fb$(100)

for x=1 to 100
fb$(x)=str$(x)
next x

for x=3 to 100 step 3
fb$(x)="Fizz"
next x

for x=5 to 100 step 5
fb$(x)="Buzz"
next x

for x=3*5 to 100 step 3*5
fb$(x)="Fizz"+"Buzz"
next x

for x=1 to 100
Print fb$(x)
next x

Am going to extend to 1 to 1,000,000 and get some timings --- interested to know if the variant without the if's is quicker....

Not what I would write it I wanted someone else to maintain it:

For i = 1 To 100
t = i Mod 3
f = i Mod 5
If Not t Then ? "Fizz";
If Not f Then ? "Buzz";
If t * f Then ? i;
Print
Next

In Verion 5.06.00b4 onwards

for i=1 to 100
print choice(i mod 15=0,"FizzBuzz",choice( i mod 3=0,"Fizz",choice(i mod 5=0,"Buzz",i)))
next i

Untested, but with latest firmware this might do it too:

For i = 1 To 100
Print Choice(i Mod 3, Choice(i Mod 5, Str$(i), "Buzz"), Choice(i Mod 5, "Fizz", "FizzBuzz"))
Next
