C++: binary std::string to decimal

Question

I want to convert 64 bit binary string to 64 bit integer (unsigned). Is there any library function to do that in C++ ?

Edit:

I use:

main()
{
std::string st = "010111000010010011000100010001110110011010110001010111010010010110100101011001010110010101101010" ;

uint64_t number;
number = strtoull (st.c_str (),NULL,2);
cout << number << " " ;

char ch = std::cin.get();
cout << ch ;


   return 0;
}

Answer 1

You can use strtoull() function with base 2 (there is an example if you follow the link).
