Error: Range-based loops are not allowed in C++98

[ChaoticFactor]

// range-based for loop
#include <iostream>
#include <string>
using namespace std;

int main ()
{
  string str {"Hello!"};
  for (char c : str)
  {
    std::cout << "[" << c << "]";
  }
  std::cout << '\n';
}

Why does this code give me 2 errors, 1 saying "Error: Range-based loops are not allowed in C++98" and another saying "in C++98 'str' must be initialised by contrusctor, not by '{...}""

I have tried installing tdm-gcc and searching the web, no specific answers. What can I do to fix this?

you should enable -std=c++11 when compiling
eg :

g++ main.cpp -std=c++11

make sure though that the compiler supports C++11 by:

g++ --version

4.7 or higher should be fine (i think)

Sorry if this is stupid, but can you please tell me how to do this?

Are you using an IDE ?

[ChaoticFactor]

Yes, I am using Code::Blocks version 12.11.

Right click your project in the left pane -> build options -> compiler settings -> check the box "enable support for c++ 11 standard" or something similar

Thank you so much!
