Logic of This Program :

In this program we are accepting the decimal number from the user and decimal number is converted into the equivalent octal number with simple steps –

Steps to Convert Decimal to Octal :

  1. Accept the given decimal number
  2. If the number is less than 8 the octal number is the same
  3. If the num > 7 then Divide the number with 8
  4. Write down the remainder
  5. Do steps 3 and 4 with the quotient till that quotient is less than 8
  6. Write the remainders in reverse order (bottom to top)
  7. The resultant is the equivalent octal number to the given decimal number
