Write a program in C to check whether a user given number is Palindrome or Not. code example
Example 1: Write a program to check whether inputted string is palindrome or not.
#include <stdio.h>
#include <string.h>
int main()
{
char s[1000];
int i,n,c=0;
printf("Enter the string : ");
gets(s);
n=strlen(s);
for(i=0;i<n/2;i++)
{
if(s[i]==s[n-i-1])
c++;
}
if(c==i)
printf("string is palindrome");
else
printf("string is not palindrome");
return 0;
}
Example 2: Write a C program to check whether the string is a palindrome without using string functions.
#include <stdio.h>#include <string.h> int main(){ char text[100]; int begin, middle, end, length = 0; gets(text); while ( text[length] != '\0' ) length++; end = length - 1; middle = length/2; for( begin = 0 ; begin < middle ; begin++ ) { if ( text[begin] != text[end] ) { printf("Not a palindrome.\n"); break; } end--; } if( begin == middle ) printf("Palindrome.\n"); return 0;}
