How to state the input of a binary number

#1

I am using the for loop in this problem, what variable do i use to represent the binary number the user inputs(considering i will have to multiply each digit with a different factor of 2)

#2

Hey @crunchybanana
Input it as a string
And
u can use str[i]-‘0’ to convert it to digit before multiplying by 2

#3

I haven’t studied strings yet, should I complete the rest of the course and then attempt these problems?

#4

You know character array ?'if u do then input it as character array
Or array of integers and itterate over it

If u havent studied arrays as well then skip this problem for now :slight_smile:
