Thread: Splitting string in chunks of 2 characters

I have a string of type std::string, and I want to split it so that 210100 would become 21 01 00 in an array of strings of type:

Code:

std::string name[] = {"21","01","00"};

However, I have no idea of how to do this in C++

Thanks in advance

        out.push_back(std::string(str, i, 2));
    }
}

Thanks much, I have a few questions though.

This function works with two arguments, the original string and the final string (result). It seems to be like the out string is of type vector, but what it is. I also want to know if there's any way I can make it a std::string.

Thanks much

Is there a way to make a vector an array of strings?

Thanks

Code:

std::string greetings[] = {"hey","hi","hello"};

Is this a vector?
