C++ String Variable Declaration

Question

I'm having some trouble declaring a string variable. Code and the errors are here: http://pastebin.com/TEQCxpZd Any thoughts on what I'm doing wrong? Also, please keep it platform independent. Thanks!

#include <stdio.h>
#include <string>
using namespace std;

int main()
{
    string input; //Declare variable holding a string

    input = scanf; //Get input and assign it to variable
    printf(input); //Print text
    return 0;
}


Getting this from GCC:

main.cpp: In function ‘int main()’:
main.cpp:53:10: error: invalid conversion from ‘int (*)(const char*, ...)’ to ‘char’
main.cpp:53:10: error:   initializing argument 1 of ‘std::basic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>::operator=(_CharT) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>, std::basic_string<_CharT, _Traits, _Alloc> = std::basic_string<char>]’
main.cpp:54:14: error: cannot convert ‘std::string’ to ‘const char*’ for argument ‘1’ to ‘int printf(const char*, ...)’

You are mixing c++ and c I/O. In C++ this is,

#include <string>
#include <iostream>

int main(void)
{
   std::string input;
   std::cin >> input;
   std::cout << input;
   return 0;
 }
