Anybody help me with reading a user inputed binary say like 10 would equal 2... I need to go from the first while loop, to the second. I am lost, and dont know what to do. It only reads the first int , how do i move to the second digit in the int?



CODE
#include <iostream>
using namespace std;

int main()
{
unsigned number;
unsigned count= 0;



cout<<"Please enter in a binary number, and I will give you the number ";
cout<< "in decimal form"<<endl;
cin>>number;
while (number=number%10)
{
if (number == 0)
   count = count + 0;
    if(number==1)
            count = count + 1;
break;
}

while(number=number%100)
{
  if (number == 0)
     count = count + 0;
  if (number == 1)
     count = count +2;
     break;
}

cout<<count;


system("pause");
return 0;  
    
}

what exactly are you trying to do at each stage of the algorithm? you need to comment your code to make it clear what each step is (supposed) to be doing.

the start of your first while loop is given by while (number=number%10). this is an assignment expression, not a logical expression - you are assigning the value of number%10 to number. since this is "true", in a way, the loop executes. however, i don't think this is what you mean to do.

please comment the code and explain the intent of the algorithm, in terms of how the routine proceeds through each step.
