A string reverse would be useful for debugging, or as an alternate way to write the loop.String reversal function reverses the entered string i.e if the user enters a string “reverse” as input then it will be changed to “esrever”. Strrev function reverses a given string in C language under the header file string.h.Note: A string which remains the same even after the reversal is called as palindrome string. The reversed string is: zyxwvutsrqponmlkjihgfedcbaExample – C Program – Reverse String using pointersAnother way of accessing a contiguous block of memory, instead of with an array, is with a pointer. Since we are talking about strings, which are made up of characters, we’ll be using pointers to characters i.e char.s. However, pointers only hold an address, they cannot hold all the characters in a character array.

This means that when we use a char. to keep track of a string, the character array containing the string must already exist. C program to reverse a string using pointers is given below.

The following program to find reverse a string has been written in Five different ways. If you do have any doubts please do let us know. Java program to find a reverse a string – Using Static Method. Using Array. Using Recursion – In case if you have no idea. Using While Loop. Using For Loop –.

Using Word by WordReverse A String – Using Static Method1) String reverse(String s) is the static method This method contains the logic to reverse the string.2) Create the object for the class ReverseofaString and call the static method with the object as rev.reverse(str)) by passing the given string. Reverse of a String is: gnirtSJava Code Reverse A String – Using Array1) We are using a character array to reverse the given string.2) Read the entered string using scanner object scan.nextLine and store it in the variable str. We are converting the string an to character array the string class method toCharArray and initialized to char ch.3) j=length of the array, for loop iterates from i=length of the array to i0.

The loop prints the character which is at the index i-1 of the array “ch” i.e. It prints the characters from the last index of the char array.
