This code is very, very simple, but I was wondering how it could be improved:

#include <iostream>
int main() {
 std::string input;
 std::getline(std::cin, input);
 for(int i = 1; i <= input.length(); i++){
 std::cout << input[input.length() - i];
 }
 std::cout << '\n';
 return 0;
}

This code takes a string input, and prints it backwards. For example:

This will be printed backwards.

Becomes:

.sdrawkcab detnirp eb lliw sihT

Given the simplicity of this code, is there a way to optimize it? I understand that since it is very short, it will run fast no matter what. However, I hate inefficiencies in code, and I want to help improve the way that I write code.

This is related to, but not copied directly from, this SO answer. (I only found this SO answer after writing the code)
