Introduction
Palindromes are words or phrases that read the same in both directions. Ex: EYE. We can find the given word is palindrome or not by using a C Program.
/* Write a C program to determine if the given string is a palindrome or not */ #include<stdio.h> #include<string.h> enum Boolean{false,true}; enum Boolean IsPalindrome(char string[]) { int left,right,len=strlen(string); enum Boolean matched=true; if(len==0) return 0; left=0; right=len-1; /* Compare the first and last letter,second & second last & so on */ while(left<right&&matched) { if(string[left]!=string[right]) matched=false; else { left++; right--; } } return matched; } int main() { char string[40]; clrscr(); printf("****Program to test if the given string is a palindrome****\n"); printf("Enter a string:"); scanf("%s",&string); if(IsPalindrome(string)) printf("The given string %s is a palindrome\n",string); else printf("The given string %s is not a palindrome\n",string); getch(); return 0; }
