C++ Printing a string in reverse using a for loop

Question

I have a program that prints out the characters of a string using a for-loop. It must also print the same characters in reverse, which is where I\'m having problems. Can someone

Answer 1

You could use reverse iterators

#include 
#include 

int main() {
  std::string myAnimal;

  std::cout << "Please enter the name of your favorite animal.\n";
  std::cin >> myAnimal;

  // Iterate in reverse order
  for(auto c = myAnimal.rbegin(); c != myAnimal.rend(); ++c) {
    std::cout << *c << std::endl;
  }
}

Note that you have to increment the variable 'c' (and not decrement it) since this is a reverse iterator.
