C++ version question, about " for(char c : str) ".

[iitsmel]

What happened:

After I typed in this code below, there'a an error. Which I think it is not supposed to appear.
Other reference I found online.

Code

for (char c : str) {
dosomethingto(c);
}

Error

expected a ';' // I think it means ':' supposed to be ';'

This is supposed to work (and works for me), but you need to make sure your cppStandard is set to c++11 or newer. Run C/C++: Log Diagnostics to see what is being used. Also, the "4.2.1" appears to reference a g++ header for an old compiler that doesn't support C++11.

I saw what's going on! My C++ standard version is 98. After I switched to 11, problem fixed! Thank you!
