Question

Write a program to convert decimal number to binary.

Answer 1

Repeatedly divide the decimal number by 2 and store each remainder in reverse order.

n = int(input("Enter a decimal number: "))
binary = ""

if n == 0:
    binary = "0"
else:
    while n > 0:
        binary = str(n % 2) + binary
        n //= 2

print("Binary number =", binary)
