Dear friends,
I have an assignment to convert from binary to decimal... I know how to do it but only thing is I need to know how many digits are stored in my variable, for example :
110101
so if somehow I know there is 6 numbers I can make my loop and convert it to decimal very easy.
Thanks.

That's only if the variable is stored in a string. If it's stored in an int, you can use a combination of modulus (%) and division (/) in a loop to do the conversion and to figure out how many digits there are. Come to think of it, you can probably do it with just division.
For example, to count the number of binary digits:
Code:int number = 42; int digits = 0; while(number) { digits ++; number /= 2; }

That should be
notCode:number /= 10
Code:number /= 2
That should beOriginally Posted by KBriggs
notCode:number /= 2;
Code:number /= 10;
Unless one really wants to deal with negative integers, it may be better to use say, unsigned int, and initialise digits to:
in order to account for the case where the number is 0.Code:unsigned int digits = number == 0;

Haha oops I was thinking in decimal
