This is a simple C program which can check whether the word or number entered by the user is palindrome or not. Rather than using longer mathematical algorithms, it simple uses 3 direct commands that are:

1. strcpy()
2. strrev()
3. strcmp()

The C program is given below:

/*
Program to check for palindrome number/word

#include <stdio.h>
#include <conio.h>

int main()
{
    char word[10],temp[10];
    printf("Enter the word/number to be checked for Palindrome\n");
    gets(word);
    strcpy(temp,word);
    strrev(temp);
    if(!strcmp(word,temp))
      printf("\nPALINDROME");
    else
      printf("\nNOT PALINDROME"); 
    getch();
    return 0;
}
