Code Explanation :

This program takes as input a binary number, and converts it to a decimal number.

  • Take a binary number and store it in the variable num.
  • Initialize the variable decimal_val to zero and variable base to 1.
  • Obtain the remainder and quotient of the binary number. Store the remainder in the variable rem and override the variable num with quotient.
  • Multiply rem with variable base. Increment the variable decimal_val with this new value.
  • Increment the variable base by 2.
  • Repeat the steps 3, 4 and 5 with the quotient obtained until quotient becomes zero.
  • Print the variable decimal_val as output.


Step 1 : Start

Step 2 : Declare variables num, binary_val, decimal_val, base and rem

Step 3 : Initialize decimal_val = 0 and base  = 1

Step 4 : Take input and stored on num

Step 5 : Set binary_val = num

Step 6 : Repeat this process until num > 0
        6.1 : rem = num % 10
        6.2 : decimal_val = decimal_val + rem * base
        6.3 : num = num / 10
        6.4 : base = base * 2

Step 7 : Print decimal_val

Step 8 : End
