C++ Program to Reverse a String and Check Palindrome

✅ C++ Program to Reverse a String and Check Whether It Is a Palindrome

#include <iostream>
#include <string.h>
using namespace std;

void rev(char str[]) {
    int start = 0, end = strlen(str) - 1;
    int temp;
    while (start < end) {
        temp = str[start];
        str[start] = str[end];
        str[end] = temp;
        start++;
        end--;
    }
}

void pal(char str[]) {
    int start = 0, end = strlen(str) - 1;
    while (start < end) {
        if (str[start] != str[end]) {
            cout << "No. String is not palindrome:\n";
            return;
        }
        start++;
        end--;
    }
    cout << "Yes. String is palindrome:\n";
}

int main() {
    char str[100];
    cout << "Enter the string:\n";
    cin.getline(str, 100);
    cout << "Before reverse:\n";
    cout << str;
    cout << "\nAfter reverse:\n";
    rev(str);
    cout << str << "\n";
    pal(str);
}
  

📘 Explanation:

This program uses two user-defined functions:

• rev() — reverses the given string manually by swapping characters from start and end.
• pal() — checks whether the string is palindrome by comparing characters from both ends.

The program uses cin.getline() to take a string input (including spaces) and strlen() from the string.h library to find string length.

🧾 Sample Output:

Enter the string:
level
Before reverse:
level
After reverse:
level
Yes. String is palindrome:
