C Program To Reverse a String
Learn How To Reverse a String in C Programming Language. We have described different versions of String Reversal Program in C Language.
strrev() method is defined in the string.h header file. It is therefore, a Library Function. strrev() method is used to reverse any given string. A String is primarily an Array of Characters.
If you want to input a Multi – word String from the user, you have to use the following scanf() method.
1 | scanf("%[^\n]%*c", string); |
If you want to enter only a single word String, then you can use the following scanf() method.
1 | scanf("%s", string); |

Thanks for so easy methods of reversing a string. Can we use reverse a string using Pointers in C?
Yes! Definitely! We can use Pointers in Strings! In fact, many methods of manipulation in string uses pointers!
What is better? Reversing a String using Arrays or Reverse a String Array using Stack Data Structure. However, this C program seems more easy in implementation.
Stack is also an implementation of array. I would suggest you to understand the logic in both the C Programs To Reverse a String. Even if you know one method, it would be more than enough.
