Question

I really need help with the code for this, in C++ please, I know there's a similar question but the answer isn't correct :[ A palindrome is a string that reads the same forwards and backwards (ignoring spaces, punctuation, and capitalization). Examples are the familiar ``If I had a hi-fi,'' the grander ``A man, a plan, a canal, Panama,'' and ``Some men interpret nine memos.'' So the goal: Design, implement, document, and test a program that reads a line of input from the terminal window and reports whether or not that line is a palindrome. The object of this project is to review and exercise C++ in general and arrays in C++ in particular. Input: An input line may contain any characters, though only letters are relevant in palindromes. Upper-case and lower-case letters are considered the same; 'A' = 'a'. For convenience, the maximum length of the input is 80 characters. Output: The program will prompt for the input line---a candidate palindrome---and will report whether or not the line is a palindrome. Errors: The program may assume that the input is as described. It need not detect any errors. Example: Several runs of the program might look like this: csh> pal Enter a line that might be a palindrome: Madam I'm Adam. The string is a palindrome. csh> pal Enter a line that might be a palindrome: Able was I ere I saw Elba. The string is a palindrome. csh> pal Enter a line that might be a palindrome: Go hang a salami, I'm a lasagna hog. The string is a palindrome. csh> pal Enter a line that might be a palindrome: This is another candidate string. The string is NOT a palindrome. PLEASE INCLUDE/ REQUIRED TO BE A COMPLETE ANSWER: Use arrays of characters to hold any strings that the program manipulates, and terminate strings within those arrays with the null character '\0'. Include at least one function. Helpful direction/ tips: Read the input one character at a time and preserve only the letters; they're all that's interesting. Note the iostream.h function get( ), which reads exactly one character, including the blank. The following loop reads all the characters in an input line, one at a time, into the variable ch. char ch; . . . cin.get(ch); while ( ch >= ' ' ) { < Do something with ch. > cin.get(ch); } When designing tests for your program, note that a string that contains no letters is a palindrome, as is an empty string.

If you have any doubts, please give me comment...

#include <iostream>

#include <cctype>

using namespace std;

#define MAX_LINE 80

int main()

{

char str[MAX_LINE];

char ch;

int n = 0, i;

cout<<"Enter a line that might be a palindrome:"<<endl;

cin.get(ch);

while (ch >= ' ')

{

if (isalpha(ch))

{

str[n] = tolower(ch);

n++;

}

cin.get(ch);

}

str[n] = '\0';

bool isPal = true;

while (i < n / 2)

{

if (str[i] != str[n - i - 1])

{

isPal = false;

break;

}

i++;

}

if (isPal)

cout << "The string is a palindrome." << endl;

else

cout << "The string is NOT a palindrome." << endl;

return 0;

}
