Recently I've been trying to write a bit of code that will take a string, for example "This is a string", and returns the string with the contents in reverse order, such as "gnirts a si sihT". I'll only post the function that will do this.

Currently, my idea is to use a loop to extract individual characters, starting from the last one, from the original string and add them to another string. Obviously, this isn't working, as the arrays aren't allowing variables to be used as markers.

string reverse(string line)
{
	size_t len = line.length();
	string clean;
	for (size_t i=len; i > 0; i--)
	{
		clean[len-i] = line[i];
	}
	return clean;
}

I apologize for my inept coding. I've only been learning C++ for two months. Any help or advice would be appreciated.

try this:

string reverse(string line)
{
	int len = line.length()-1;
	string clean;
	while( len >= 0)
	{
		clean += line[len--];
	}
	return clean;
}
