C Program to Reverse a String Using Recursion - GeeksforGeeks
January 24, 2026 - The string can be reversed by using two pointers: one at the start and one at the end. Swap the values of these two pointers while moving the pointers towards each other. Let’s take a look at an example: ... #include <stdio.h> #include <string.h> ...

You need to modify the string, i.e. the input buffer to reverse(), instead of just printing it.
Doing this recursively seems a bit obnoxious, but should of course be possible.
Basically, I guess the printing becomes an assignment, something like this:
- Base: The reversal of an empty string is the empty string.
- Step: The reversal of a string begins by swapping the first and last characters, then recursing over the remainder of the string.

Reverse a sentence using recursion
It works to reverse the sentence, because of the order of two inner lines of reverseSentence().eg, if printf was called before recursing, then the sentence would print out in-order. Because the order is to recurse first, then printf, the first character captured is the last to be printed to the screen. More on reddit.com

September 26, 2022[C++] Errors when trying to write a reversing string with recursion
but I keep getting errors and my code won't compile.
Tell us those errors.
I'm coding in vim and I don't know how to copy/paste.
Put set clipboard=unnamed somewhere in your vimrc. Then the system-wide clipboard (or X clipboard on Linux) will be used for yanking and pasting by default in vim. I like Shift+v for visual line selection, then y for yanking the selection.
(However, vim masters would tell you to learn motions so that you wouldn't have to use the visual mode, and they'd also tell you to read :help registers.)

C Program: Get reverse of a string - w3resource
The variable i is used to keep track of the index of the reversed string and is initialized to 0. The variable revstr is used to store the reversed string. The function checks if the first character of the input string is not null. If it is not null, the function calls itself recursively with the input string pointer incremented by 1 (i.e., the address of the second character).

Your string is actually 6 bytes long - 'h', 'e', 'l', 'l', 'o', '\0'. The last character is a null byte, which is a string terminator. It signals to functions like printf or strlen where the string ends. When you call reverse, it reverses the entire string, so now the terminator is the very first byte, and printf interprets that as an empty string.
There are two ways to fix this. Either make the index that you pass to reverse one smaller (call reverse(a, 0, n-2)), or use strlen instead of sizeof (int n = strlen(a)).

Always remember, the array index for nth element will be n-1.
Your array has 6 elements, so the index will run from 0 to 5, the last [6th] elemst being the NUL terminator.
As per your logic, the NUL terminator becomes the first element in the reversed array, hence no output as string.
Following the logic, your first call to reverse() should be reverse(a,0,n-2); to avoid the NUL being put as the first element in reversed array.

We will first call reverse function by passing following parameters reverse("ORANGE", 0, 5). Then reverse function will swap the positions of character 'O'(leftmost character) and 'E'(rightmost character) and recursively calls itself to reverse inner substring as reverse("ERANGO", 1, 4) and so on.

It works to reverse the sentence, because of the order of two inner lines of reverseSentence().eg, if printf was called before recursing, then the sentence would print out in-order. Because the order is to recurse first, then printf, the first character captured is the last to be printed to the screen.
