Everything seems to be correct from my perspective. heres the program: Code: /*c program to check whether a string is palindrome or not*/
#include<stdio.h>

int main(void) {
char str[30];
int i,j,flag=0;

here is my code, the issue is its not determine if the value is a palindrome or not.

I am trying to check a string to be a palindrome. I have tried using for loop but I am looking for most efficient way.

So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?

I am trying to create a simple palindrome program. I get the error string subscript out of range. I believe the error is either in the while or for loops.

I am supposed to take the three string lines from a text file and then individually reverse them and state whether or not they are a palindrome. I have the three lines from the text file into string variables already but I am not sure on how to reverse them and then see if they are the same reversed(palindrome)

This question was asked in Hackerrank. [URL] ....
I am able to get correct output upto a input of 50000 character string, but not for 100000 character string.
I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {
string str;

wrote this program to check if a string is an integer. It checks for + or - sign at the front of it, but it spat out some errors.I think I broke it.Here is the code:

This is program is suppose to check if a phrase is a palindrome or not.I need to write a function definition for _Bool palindromeness(char str[])but I am having a tough time figuring that part out. I am brand new to programming..this is my first class and I am just learning arrays and pointers.

I had an assignment to do a palindrome program but im stuck in this part.
"This c-string will be sent to a function that will remove all spaces and punctuation marks from its c-string as well as change any uppercase letters to lowercase. Use string tokens to eliminate the spaces & punctuation marks. Make sure you include the NULL as you concatenate the tokens into a c-string. Then copy back into the original c-string for the pass by reference."
void tokenptr(char drome[]) {
char *token;
size_t i;
token = strtok(drome, " ,.!:;?");
while (token != ' ') {
[Code] .....
I'm pretty sure I did that part except how can i pass this cstring back to main? We really haven't even touched much of pointers except to use strtok().
My assignment is to make a program that tests whether something is a Palindrome or not using a recursive function. Also, in order to test what type the Palindrome is (if it is indeed a palindrome) I'll need to merge sort it. Now alphabet characters, spaces, and numbers are all allowed, as long as the spaces line up with the spaces in the original input. And yes this is user inputted. I can show you what I've got so far and then I'll tell you what my problem is.
#include <iostream>
#include <istream>
#include <string>
#include <string.h>
#include <conio.h>
using namespace std;
/************To Test if Palindrome*******************/
bool IsPalindrome(char *str, int size) {
if( str[0] == str[size-1]);
[Code] .....
Now my problem is that I can't seem to get the test to work correctly. Since the word is user inputted I don't have any way of knowing the size so that kind of complicates it a little bit. The other thing is I was told by my professor that I need a boolean flag to make it work, and I need to set the value to the return of the IsPalindrome function. I'm not sure how to do that. I also don't haven't been able to add in the MergeSort yet, so the Order and Type don't really work correctly because I'm not sure how to get int len for it. (len is length)

Write a function palindrome that takes a vector parameter and returns true or false according to whether the vector does or does not read the same forward as backward (e.g., a vector containing 1, 2, 3, 2, 1 is a palindrome, but a vector containing 1, 2, 3, 4 is not).

#include <vector>
#include <iostream>
using namespace std;
void palindrome(vector<int>);

I have an assignment where i have to make a palindrome program. As you can see i have already done the basic palindrome prog, however i am now stuck since the program goes into a infinite loop whenever a word with whitespaces is added.
I have also tried searching for methods online however they do not seem to work for me...

length = strlen(palin);
for (int i = 0, p = length-1; p>i; i++, p--) {
if (palin[i] == ' ')

I usually check if a bit is set using:
Code: bit = (number >> n) & 1; where `n` is the bit I want to check...
But I came across a stackoverflow answer saying:
bit = number & (1 << x); will not put the value of bit x into bit unless bit has type _Bool (<stdbool.h>).
Otherwise, bit = !!(number & (1 << x)); will..
So why is this? why the double !?
The reason being is that it says that my program is right

#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#define NFlights 10
struct date {
int month;
int day;

Q. In context of C language syntax checking, which of the following can be modeled using Finite Automata?
(A) Detecting proper termination of an instruction.
(B) Detecting balance of parentheses.
(C) Detecting initialization of a variable.
(D) None of the above.
