Write a C Program that asks the user to input a string and then the user is prompted back whether the input string is a “Palindrome Word” or not. (A Palindrome Word reads the same backward or forward, eg. madam, racecar, etc.)
Your program should contain a function that accepts the input string from the main function and returns a value indicating whether the input string is a Palindrome or not.
Use Pointers to traverse the string.
#include<stdio.h>
#include<string.h>
#include<stdbool.h>
bool isPalindrome(char str[])
{
// point to the starting character
char *start = str;
// point to the ending character
char *end = str + ( strlen(str) - 1 );
// loop untill start pointer is before end pointer
while( start < end )
{
// if the current character from start and end are not equal
if( *start != *end )
return false;
// update the pointers
start++;
end--;
}
return true;
}
int main()
{
char str[100];
printf("Enter a string : ");
// read complete line
gets(str);
// if it is palindrome
if( isPalindrome(str) )
printf("it is palindrome.");
// if it is not palindrome
else
printf("it is not palindrome.");
return 0;
}

A palindrome is a word, phrase, number, or other sequence of symbols or elements that reads the same forward or reversed. Examples: “Dad”, “Anna”, “Never odd or even”, etc. For this problem, we will only consider a string to be palindromic if its combined alpha-numeric characters (‘A’-’Z’, ‘a’-’z’, and ‘0’-’9’) can be read the same both forward and backward, by skipping all other non-alphanumeric characters.Write the following function that takes a user input string, computes, and determines whether the input is palindromic or not...
palindrome is a string that reads the same both forward and backward. C++ For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameters.
C language: Write a program that uses a function to check if a user entered string is a palindrome. Based on the return value of the function, the results are printed in the main() function. (do not print results in function to check for palindrome) A palindrome reads the same forward as backward for example tacocat or civic.
C++ A palindrome is a string that reads the same backward as forward. For example, the words mom, dad, madam and radar are all palindromes. Write a class Pstring that is derived from the STL string class. The Pstring class adds a member functionbool isPalindrome( )that determines whether the string is a palindrome. Include a constructor that takes an STL string object as parameter and passes it to the string base class constructor. Test your class by having a main...

In C++ Write a program that: Gets a string from cin Prints TRUE if the string is a palindrome, FALSE otherwise, all uppercase, followed by endl. Palindrome reads the same backward as forward, e.g., madam.
A palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. In this program, ask the user to input some text and print out whether or not that text is a palindrome. Create the Boolean method isPalindrome which determines if a String is a palindrome, which means it is the same forwards and backwards. It should return a boolean of whether or not it was a palindrome. Create the method reverse...
For this assignment, you will create a program that tests a string to see if it is a palindrome. A palindrome is a string such as “madam”, “radar”, “dad”, and “I”, that reads the same forwards and backwards. The empty string is regarded as a palindrome. Write a recursive function: bool isPalindrome(string str, int lower, int upper) that returns true if and only if the part of the string str in positions lower through upper (inclusive at both ends) is...
Write a program that reads each word from A1.txt and check if it's a palindrome or not. Show your output in the file Bl.txt. The total number of words in the file can change. You must use c-string or character arrays. Using String datatype and strrev() function are not allowed in this problem. "A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward." (Wikipedia) Sample Input: series madam Sample Output: yes
write a loop that processes a string and returns true if the string is a palindrome and false if it is not. A String is a palindrome if it is spelled the same forward as it is backward. For example, the words “joe”, “ age”, “pokemon”, “b”, “kayak” and “racecar” are all palindromes. C++ I wrote a sample but not compiling... #include"stdafx.h" #include<iostream> #include<string> int main() { Int x = 0; Int y= 0; string word = “racecar” x= 0;...
