Sorry, I can't understand your question.
Binary value... of what? The same counter-question about "to decimal value"...

nothing fancy, if you know how to convert a binary representation to decimal on paper...just implement that! i'd use a string to input 1's and 0's but you can use a long long or something using a simple algorithm to seperate digits:

``````#include <iostream>

using namespace std;

int main( void )
{
long long num; int result = 0, pow = 1;
cin >> num;
while( num > 0 ) {
result += ( num % 10 )*pow;
pow <<= 1;
num /= 10;
}
cout << result << endl;
return 0;
}``````

thank you so much for responding
