In this video, we’ll explore a C program that reverses a given string step-by-step. Using simple logic and the strlen function, this code is designed to reverse a string without using any built-in reverse functions. Here’s how it works:

Code Explanation:

1. Initializing the String:
We start with a string "Elkick Academy", which we store in the str array.
Using strlen(str), we calculate the length of the string and store it in the len variable.

2. Creating the Reverse Logic:
We declare a new character array rev[len] to store the reversed string.
Using a for loop, we iterate through each character of the original string str from the last index to the first.
For each index i, we use str[len - i - 1] to access the character from the end of the string.
This character is then assigned to rev[i], effectively reversing the string.
Printing Each Step:

During each iteration of the loop, printf outputs the current index and character to show how the characters are placed in reverse order.
Displaying the Result:

After the loop completes, we print the rev array, which now holds the reversed string.

Output:
-----------
For the input "Elkick Academy", the program will print each character in reverse order as it builds the reversed string, and finally display "ymedacA kciklE."
This program is a great example of manipulating strings in C and understanding character arrays. Let’s dive into the code and see how each part contributes to reversing the string efficiently.
