Fizzbuzz function Javascript

Science & Technology
1

I came across this test on codeacademy where you have to write a function that returns “fizz” for a number that is divisible by 3, “buzz” for a number that is divisible by 5 and “fizzbuzz” for a number that is divisible by both 3 and 5. Unfortunately free codeacademy doesn’t really have that much support when one is stuck na google pia haisaidii sana. Hii kitu inaandikwa aje?

very simple

         static void runtest()
        {
            for (int i = 1; i <= 25; i++)
            {
                string szFizzBuzzTestResult = fizzBuzzTest(i);
                if (!(String.IsNullOrEmpty(szFizzBuzzTestResult)))
                    Console.WriteLine(szFizzBuzzTestResult);                    
            }
        }
        static string fizzBuzzTest(int i)
        {
            string szresult = string.Empty;
            if (i % 3 == 0 && i % 5 == 0)
                szresult= (string.Format("{0} = fizzbuzz", i));
            else if (i % 3 == 0)
                szresult= (string.Format("{0} = fizz", i));
            else if (i % 5 == 0)
                szresult=(string.Format("{0} = buzz", i));
            return szresult;
        }

Indeed very simple

Why do I sense some sarcasm, it’s basic modulo arithmetic

:slight_smile:

For beginners like me, sio rahisi hivyo. Ukaona vile nilifanya yangu

How did you do it. Post hapa nione.

7

ungeweka ya user kuweka input yake…But wewe this is java…
not javascript

8

var x = prompt(“Please enter a number of your choice”);
if (x % 3 == 0)
{
console.log(“fizz”);
}
else if (x% 5 == 0);

{
console.log(“buzz”);
}
else if (x % 15 == 0) {
console.log(“fizzbuzz”);
}
else {
console.log(“number not divisible by both 5 and 3”)
};

which language??

That’s not Java, it’s C#. And what matters Is the logic, modulo works for all programming environments

And by the way your sample code has a bug. Biggest dummy mistake. No offense :slight_smile:

11 
function fizzBuzz() {
var numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];
for(var i = 0; i<=20; i++) {
  var fizz = numbers[i]%3===0;
  var buzz = numbers[i]%5===0;
  var fizzBuzz = nmbers[i]%5===0 &&numbers[i]%3===0;
  if(fizzBuzz){
    console.log("FizzBuzz");
  }
  else if(fizz) {
    console.log("Fizz");
  }
  else if(buzz){
    console.log("Buzz");
  }
  else {
    console.log(numbers[i]);
  }
}

}

Javascript and Python

Here is cpp

#include <iostream>

using namespace std;

string fizzbuzz(int testValue)
{
    if ((testValue % 3 == 0) && (testValue % 5 == 0))
        return "fizzbuzz";
      
    if (testValue % 3 == 0)
        return "fizz";
  
    if (testValue % 5 == 0)
        return "buzz";
      
    return "";
}

int main()
{
  
   for (int i = 0; i < 100; i++)
   {
       cout << i << "=" << fizzbuzz(i) << "\n";
   }
  
   return 0;
}

@shadow-walker This is how I would’ve done it.
PS: 0%n == 0 every time.

#include <iostream>

using std::string;
using std::cout;
using std::endl;

string fizzBuzz(int testValue) {
    if ( testValue == 0 )
        return "";

    string result;
    if ( testValue % 15 == 0 ) {
        result = "fizzbuzz";
    }
    else if ( testValue % 3 == 0) {
        result = "fizz";
    }
    else if (testValue % 5 == 0) {
        result = "buzz";
    }

    return result;
}

int main(void) {
   for (int i = 0; i < 100; i++) {
       cout << i << "=" << fizzBuzz(i) << endl;
   }
   return 0;
}

Javascript:

fizzBuzz = function (num) {
    if ((num % 3 == 0) && (num % 5 == 0)) {
        return "FizzBuzz";
    } else if (num % 3 == 0) {
        return "Fizz";
    } else if (num % 5 == 0) {
        return "Buzz";
    } else {
        return num;
    }
};
