Program to check whether string is palindrome or not without using library function
#include<stdio.h>
void main()
{
char s[20];
int i=0, len, flag = 0;
printf("\nEnter s1: ");
gets(s);
/*To
find the length of the string*/
while(s[i]!='\0')
{
i++;
}
len = i;
for(i=0; i<len/2; i++)
{
if(s[i] != s[len-i-1])
{
flag = 1;
break;
}
}
if(flag == 0)
printf("\nString is
palindrome.");
else
printf("\nString is not
palindrome.");
}
Output:
Enter s1: abcba
Strings is palindrome.
