Input
Enter a Octal number : 17Output
Decimal equivalent of given number : 15 Input
Enter a Octal number : 24Output
Decimal equivalent of given number : 20Step 1: START
Step 2: Enter a octal number 'num' as an input.
Step 3: Multiply each digit of num by the power of 8 and store each multiplication.
i.e Power of 8 starts from 0 to n-1 where n is the total number of digits in the num
Step 4: END
