Question

Here are my instructions for my C++ program:

Write a program that uses the
function isPalindrome given in
Example 6-6 (Palindrome). Test
your program on the following
strings:

madam, abba, 22, 67876, 444244, trymeuemyrt

Modify the function isPalindrome
of Example 6-6 so that when
determining whether a string is a
palindrome, cases are ignored, that
is, uppercase and lowercase letters
are considered the same.

The isPalindrome function from
Example 6-6 has been included
below for your convenience.

bool isPalindrome(string str)
{
int length = str.length();
for (int i = 0; i < length / 2; i++) {
if (str[i] != str[length – 1 – i]) {
return false;
} // if
} // for loop
return true;
}// isPalindrome

Your program should print a
message indicating if a string is a
palindrome:

madam is a palindrome

The lab values require that I have the following string patterns in my lab:

.+*isPalindrome\(\"Madam\"\).+*

.+*isPalindrome\(\"abBa\"\).+*

.+*isPalindrome\(\"22\"\).+*

.+*isPalindrome\(\"67876\"\).+*

.+*isPalindrome\(\"444244\"\).+*

.+*isPalindrome\(\"trYmeuemyRT\"\).+*

### Palindrome Function Testing

Below are the results of testing the function `isPalindrome`, which checks if a given string is a palindrome. A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward (ignoring spaces, punctuation, and capitalization).

#### Test Results:

1. **Code Pattern:**
- **Status:** Complete
- **Description:** Uses function `isPalindrome`

2. **Test Case 1:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "Madam"

3. **Test Case 2:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "abBa"

4. **Test Case 3:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "22"

5. **Test Case 4:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "67876"

6. **Test Case 5:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "444244"

7. **Test Case 6:**
- **Status:** Incomplete
- **Test Description:** Tested `isPalindrome` with the string argument "tRYmeuemyRT"

This list indicates that while the use of the function is implemented, several tests have not been completed to determine if the function accurately identifies palindromes in the given test cases. Further review and testing are required to ensure the function's reliability.

**Title:** Palindrome Checking Program

**Description:**

A program designed to determine if a given string is a palindrome.

**Checks:**

- **Test Case:** Incomplete
- **Description:** Test for palindromes
- **Input:** Not specified
- **Output:** "enter a string; is a palindrome"

**Results:**

- **madam is a palindrome**
- **Abba is a palindrome**
- **444244 is not a palindrome**
- **22 is a palindrome**
- **07070 is a palindrome**
- **%YYanaaYY% is a palindrome**

The program currently has 0 out of 1 checks passed, as indicated by the text "0 out of 1 checks passed. Review the results below for more details."

Users can run the checks again or submit the program for evaluation.

Follow-up Question

Your output was correct

The lab values require that I have the following string patterns in my lab:

Description

Searched your code for a specific pattern:

.+*isPalindrome\(\"Madam\"\).+*

.+*isPalindrome\(\"abBa\"\).+*

.+*isPalindrome\(\"22\"\).+*

.+*isPalindrome\(\"67876\"\).+*

.+*isPalindrome\(\"444244\"\).+*

.+*isPalindrome\(\"trYmeuemyRT\"\).+*

### Palindrome Function Verification

#### Overview
This screen provides a progress report on palindrome function testing, showcasing your development in utilizing the `isPalindrome` function with required string arguments.

#### Test Summary
- **Score:** 10.00 out of 70.00
- **Check Status:** 1 out of 7 checks passed
- **Guidance:** Review the details below for improvement suggestions.

#### Detailed Checks

1. **Code Pattern: Function Usage**
- **Status:** Complete
- **Description:** Successfully uses the function `isPalindrome`.

2. **Code Pattern: Test with 'Madam'**
- **Status:** Incomplete
- **Description:** The function `isPalindrome` was not tested with the string argument `"Madam"`.

*Details*: The code search was for the pattern: `.*isPalindrome\(.*"Madam".*\).*`

3. **Code Pattern: Test with 'aBbA'**
- **Status:** Incomplete
- **Description:** The function `isPalindrome` was not tested with the string argument `"aBbA"`.

#### Action Points
- Make sure to run tests using specific string arguments like `"Madam"` and `"aBbA"` to verify the functionality of your palindrome checker.

#### Code Snippet
The snippet included illustrates the implementation of `isPalindrome` in C++ using string manipulation to check palindrome status with character case insensitivity.

#### Suggestions for Improvement
- Utilize the `Run checks` button to re-evaluate your code after making necessary corrections.
- Explore regular expressions for more efficient pattern matching in your tests.

> Remember: Palindromes are strings that read the same forwards and backwards, disregarding case differences. Ensure your function handles this appropriately.

The image shows a snippet of code and an output window from a programming exercise designed to identify palindromes. Here's the transcription and explanation:

---

**Output:**

- madam is a palindrome...
- abBa is a palindrome...
- 22 is a palindrome...
- 67876 is a palindrome...
- 444244 is not a palindrome...
- trYmeuemyRT is a palindrome...

**Results:**

- madam is a palindrome
- abBa is a palindrome
- 22 is a palindrome
- 444244 is not a palindrome
- trYmeuemyRT is a palindrome

**Expected Output:**

- madam is a palindrome
- abba is a palindrome
- 22 is a palindrome
- 67876 is a palindrome
- 444244 is not a palindrome
- trYmeuemyRT is a palindrome

---

**Explanation of the Code:**

The code consists of a function named `isPalindrome` which takes a string `str` as input and checks if it is a palindrome. It uses the following logic:

1. Calculate the length of the string.
2. Iterate over half of the string, comparing characters from the beginning and the end.
3. If any character pair does not match (considering case insensitivity), return `false`.
4. If all pairs match, return `true`.

**Observations:**

- The output section shows how different strings are evaluated to determine if they are palindromes.
- The "Results" section shows the actual output produced by the code.
- The "Expected Output" section provides the correct outputs for testing, which the program aims to match.

This exercise demonstrates basic string manipulation and comparison techniques in programming to identify palindromes effectively.
