How to convert a number to its octal representation in Kotlin

How to convert a number to its octal representation in Kotlin.

Here's a step-by-step tutorial on how to convert a number to its octal representation in Kotlin:

Step 1: Get the decimal number to be converted

• Decide on the decimal number you want to convert to octal. For example, let's say we have the decimal number 42.

Step 2: Define a function to convert decimal to octal

• Start by defining a function that takes in a decimal number and returns its octal representation. We can name the function decimalToOctal:

  fun decimalToOctal(decimal: Int): String {
      // code for conversion will go here
  }

Step 3: Initialize variables

• Inside the decimalToOctal function, initialize two variables: quotient and octalDigits. Set the quotient variable to the input decimal number, and initialize an empty string for octalDigits:

  fun decimalToOctal(decimal: Int): String {
      var quotient = decimal
      var octalDigits = ""
  }

Step 4: Perform the conversion

• Use a while loop to repeatedly divide the quotient by 8 until it becomes 0. Inside the loop, append the remainder (converted to a string) to the octalDigits variable, and update the quotient:

  fun decimalToOctal(decimal: Int): String {
      var quotient = decimal
      var octalDigits = ""
  
      while (quotient != 0) {
          octalDigits = (quotient % 8).toString() + octalDigits
          quotient /= 8
      }
  }

Step 5: Return the octal representation

• After the while loop, return the octalDigits variable as the octal representation of the input decimal number:

  fun decimalToOctal(decimal: Int): String {
      var quotient = decimal
      var octalDigits = ""
  
      while (quotient != 0) {
          octalDigits = (quotient % 8).toString() + octalDigits
          quotient /= 8
      }
  
      return octalDigits
  }

Step 6: Test the function

• Finally, you can test the decimalToOctal function by providing a decimal number and printing the result:

  fun main() {
      val decimal = 42
      val octal = decimalToOctal(decimal)
      println("Octal representation of $decimal is $octal")
  }

That's it! You now have a complete Kotlin function to convert a decimal number to its octal representation. You can try running the code with different decimal numbers to see the octal output.
