C++ :: Program To Check Whether Or Not A String Is Palindrome

May 20, 2013

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?

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
bool isPalin(string& palin);
string cleanUp(string& palin);

C/C++ :: Reverse A String And State If It Is A Palindrome

Mar 28, 2015

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)

Here is my code so far -->

#include <iostream>
#include <string>
#include <cctype>

[Code].....

EDIT: Ignore line 123 and down in the code. That was merely test code and will not be used.

C++ :: Determine Number Of Times Change Each Specific Character In String To Make It Palindrome

Feb 19, 2015

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;

C/C++ :: Palindrome Program - Cstrings Using Strtok Function

Feb 28, 2014

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().

C++ :: Palindrome - Program Goes Into Infinite Loop Whenever Word With White Spaces Added

Feb 9, 2013

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...

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

C :: Check To See If String From Standard Input Is Alphanumeric Or Not?

Dec 25, 2014

I'm trying to check to see if a string from standard input is alphanumeric or not. I feel as though there may be a function for this but...

Code:
for(test_pass = i; test_pass < i; i++){
if(test_pass[i] == ('1', '2', '3', '4', '5', '6', '7', '8', '9', '0'))
printf("Your password is alphanumeric!
");
}

The compiler wasn't too happy with this.

C/C++ :: String Variable - How To Check If Email Is Not Fake

Jun 4, 2014

Ii made one string variable and called it email_confirm. I used cin to get the users email but i don't know to check if the email is real.(without being connected to the internet).

For example,in PHP you can use ereg() or eregi() to see if the email is real, I mean you can see how many characters the email_confirm is made off or how many characters is used after the @ or . is used. is there any functions for this?
