What should be noted when outputting a string in reverse order in the C language?

When reversing a string in the C language, you need to be mindful of the following points:

1. Make sure the string ends with a null character ‘\0’, or errors may occur when outputting in reverse order.
2. When reversing a string, it is necessary to use a loop to iterate through each character in the string and output them in reverse order.
3. An auxiliary variable can be used to help with the process of reversing output, by taking out characters from the string one by one and outputting them in reverse order.
4. Pay attention to the size of the character array to ensure that there is no out-of-bound memory access when outputting in reverse order.
5. Remember to add a null character ‘\0’ at the end to indicate the end of the string after reversing the output.
