Nowadays, most interviewers ask the candidate to write the FizzBuzz program. So here I am, giving the 10+ programming languages FizzBuzz program examples. These examples will help you learn how to do it in the most popular programming languages.
What is FizzBuzz Program?
In the FizzBuzz program, you have to write the following logic:
- For multiples of three, print Fizz (instead of the number).
- For multiples of five, print Buzz (instead of the number).
- For multiples of both three and five, print FizzBuzz (instead of the number).
FizzBuzz Program Examples
Below are the 10+ FizzBuzz program examples from the most common programming languages.
Example 1: Using C++
#include <iostream>
using namespace std;
int main()
{
for (int i = 0; i <= 100; ++i)
{
bool fizz = (i % 3) == 0;
bool buzz = (i % 5) == 0;
if (fizz)
cout << "Fizz";
if (buzz)
cout << "Buzz";
if (!fizz && !buzz)
cout << i;
cout << "\n";
}
return 0;
}
Output:
1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz 16 17 Fizz 19 Buzz Fizz ...
Code Explanation
- The code is a loop that iterates from 1 to 100.
- The code checks if the number is divisible by 3, 5, or 15 and prints out "FizzBuzz" for numbers divisible by 3, "Fizz" for numbers divisible by 5, and "Buzz" for numbers not divisible by either of those values.
- The code will print the numbers from 1 to 100.
- If a number is divisible by 3, it will be printed as "Fizz".
- If a number is divisible by 5, it will be printed as "Buzz".
- Otherwise, the number itself will be printed.
Example 2: Using GO Lang
package main
import "fmt"
func main() {
for i := 1; i <= 100; i++ {
switch {
case i%15==0:
fmt.Println("FizzBuzz")
case i%3==0:
fmt.Println("Fizz")
case i%5==0:
fmt.Println("Buzz")
default:
fmt.Println(i)
}
}
}
The result would be the same as is in the first example.
Example 3: Using Java
public class FizzBuzz {
public static void main(String[] args) {
for (int number = 1; number <= 100; number++) {
if (number % 15 == 0) {
System.out.println("FizzBuzz");
} else if (number % 3 == 0) {
System.out.println("Fizz");
} else if (number % 5 == 0) {
System.out.println("Buzz");
} else {
System.out.println(number);
}
}
}
}
Example 4: Using JavaScript
var fizzBuzz = function () {
var i, output;
for (i = 1; i < 101; i += 1) {
output = '';
if (!(i % 3)) { output += 'Fizz'; }
if (!(i % 5)) { output += 'Buzz'; }
console.log(output || i);//empty string is false, so we short-circuit
}
};
Example 5: Using Julia
for i in 1:100
if i % 15 == 0
println("FizzBuzz")
elseif i % 3 == 0
println("Fizz")
elseif i % 5 == 0
println("Buzz")
else
println(i)
end
end
Example 6: Using Kotlin
fun fizzBuzz() {
for (number in 1..100) {
println(
when {
number % 15 == 0 -> "FizzBuzz"
number % 3 == 0 -> "Fizz"
number % 5 == 0 -> "Buzz"
else -> number
}
)
}
}
Example 7: Using LaTex
\documentclass{minimal}
\usepackage{ifthen}
\usepackage{intcalc}
\newcounter{mycount}
\newboolean{fizzOrBuzz}
\newcommand\fizzBuzz[1]{%
\setcounter{mycount}{1}\whiledo{\value{mycount}<#1}
{
\setboolean{fizzOrBuzz}{false}
\ifthenelse{\equal{\intcalcMod{\themycount}{3}}{0}}{\setboolean{fizzOrBuzz}{true}Fizz}{}
\ifthenelse{\equal{\intcalcMod{\themycount}{5}}{0}}{\setboolean{fizzOrBuzz}{true}Buzz}{}
\ifthenelse{\boolean{fizzOrBuzz}}{}{\themycount}
\stepcounter{mycount}
\\
}
}
\begin{document}
\fizzBuzz{101}
\end{document}
Example 8: Using PHP
<?php for ($i = 1; $i <= 100; $i++) { if (!($i % 15)) echo "FizzBuzz\n"; else if (!($i % 3)) echo "Fizz\n"; else if (!($i % 5)) echo "Buzz\n"; else echo "$i\n"; } ?>
Example 9: Using PL/SQL
BEGIN
FOR i IN 1 .. 100
LOOP
CASE
WHEN MOD(i, 15) = 0 THEN
DBMS_OUTPUT.put_line('FizzBuzz');
WHEN MOD(i, 5) = 0 THEN
DBMS_OUTPUT.put_line('Buzz');
WHEN MOD(i, 3) = 0 THEN
DBMS_OUTPUT.put_line('Fizz');
ELSE
DBMS_OUTPUT.put_line(i);
END CASE;
END LOOP;
END;
Example 10: Using Python
for i in range(1, 101):
if i % 15 == 0:
print("FizzBuzz")
elif i % 3 == 0:
print("Fizz")
elif i % 5 == 0:
print("Buzz")
else:
print(i)
Example 11: Using Oracle Select Statement (SQL)
SELECT CASE
WHEN MOD(level,15)=0 THEN 'FizzBuzz'
WHEN MOD(level,3)=0 THEN 'Fizz'
WHEN MOD(level,5)=0 THEN 'Buzz'
ELSE TO_CHAR(level)
END FizzBuzz
FROM dual
CONNECT BY LEVEL <= 100;
