C++ Program to Check Whether Given String is a Palindrome

Problem:- Write A C++ Program To Check String Is Palindrome Or Not or C++ Program to Check Whether Given String is a Palindrome or Check Given String is Palindrome or not in C++ or C++ Program to Check String is Palindrome or not or Program to check a string is palindrome or not or C++ Program to Check Whether String is Palindrome or C++ program to check whether given string is palindrome or not? or C++ Program to Check whether a string is A Palindrome or Not or C++ Program to Check Number is Palindrome or Not or C Program to Check if a Given String is A Palindrome.

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Logic:- What Is Palindrome?

"a word, phrase, or sequence that reads the same backward as forwards"

" Matlab Ulta Seedha Ek Saman " or " मतलब उल्टा सीधा एक समान "

Simple if the string is "MADAM" compare the First letter index of 'M' to the last letter index of 'M' and again compare to 2nd letter index to the second last letter index if both are same then continue for next upcoming letters and repeat the same process continue to repeat if all Word's are same then String Is Palindrome.

Try to Solve- Try to solve this problem for Numbers, Check weather number is Palindrome.

Solution:-


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

int main()
{
/*Visit - www.programmingwithbasics.com*/
   
    cout<<"=====================================";
    cout<<"\nVisit - www.programmingwithbasics.com";
    cout<<"\n=====================================";
    
    while(1)
    {
    char string1[20];
    int i, length;
    int flag = 0;
    cout << "\n\nEnter a String: ";
    cin >> string1;
    length = strlen(string1);
    for(i=0;i < length ;i++)
  {
        if(string1[i] != string1[length-i-1])
  {
            flag = 1;
            break;
      }
  }
  cout<<"\n\n";
    if (flag) 
  {
        cout << string1 << "==> Is Not Palindrome " << endl;
    }  
    else 
{
        cout << string1 << "==> Is Palindrome " << endl;
    }
}
    return 0;
}

Output:-

C++ Program to Check Whether Given String is a Palindrome
