error c++98
When I try to compile the example program in the tutorial for creating a range-based for loop, I get an error: 10 16 C:\Users\Public\Documents\C prog source\range based for loop.cpp [Error] range-based 'for' loops are not allowed in C++98 mode. Is this sample program supposed to work?
I am a rank beginner. Could you elaborate on
g++ -std=c++11?
where this should be placed, what each element does. Here is the code I am trying to make work.
// 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';
}
g++ -std=c++11?

How are you compiling your code? I had assumed you were using g++, but perhaps you are using another compiler?

Shows just how ignorant I am. I did not realize that there was a g++. No I am using the compiler that came with dev-cplusplus compiler that I downloaded from the net. And I thought this forum was for Cplusplus users.

Yes, this forum is for helping with learning C++ :)

Everyone learns what a compiler is at some point once they begin their journey to becoming a programmer.
In dev-cplusplus:
Go to Tools -> Compiler Options -> "Compiler" tab
Check the checkbox labeled, "Add the following commands when calling the compiler" And add in the text entry box, "-std=c++11" or if that doesn't work "-std=C++0x"
Should be something like that anyway, I haven't had Dev C++ installed for many years, so I had to look at some screenshots on Google to remember.

One aspect to also consider if you have the facilities available, is to use a more up to date and supported IDE rather than dev C++ such. as visual studio, code blocks, Xcode, Qt creator which are way ahead. Each of those wil virtually automatically give you the ability and choice to use the various forms of C++ mentioned elsewhere here. I realise some schools in different parts haven't updated from Dev so students are stuck.

Go to project->options->Compiler->Code generation and choose GNU C++ 11
