Answer:
In Python:
bin = int(input("Binary Number: "))
num = str(bin)
dec = 0
for i in range(len(num)):
dec = dec + int(num[i]) * 2**int(len(num)-i-1)
print("Decimal Equivalent: "+str(dec))
Explanation:
Note that the program assumes that the user input will be valid. So, error check was done in the program
This line gets the binary number from the user
bin = int(input("Binary Number: "))
This converts the inputted number to string
num = str(bin)
This initializes decimal number to 0
dec = 0
This iterates through the string number
for i in range(len(num)):
This converts the number to decimal
dec = dec + int(num[i]) * 2**int(len(num)-i-1)
This prints the result of the conversion
print("Decimal Equivalent: "+str(dec))
