Program to check whether the reverse string is a palindrome

 

#include<stdio.h>
#include<string.h>

int main()
{
	//declare variables
	char str1[30];
	int i,len,flag=0;
	
	printf("Enter a string:");
	scanf("%s",str1);
	
	len=strlen(str1);//get the string length
	
	for(i=0;i<len;i++)
	{
		//str1[i] is not equal to str1[len-i-1]
		if(str1[i]!=str1[len-i-1])
		{
			flag =1;
			break;//exit from if statement
			
		}
	}
	
	if(flag)
	{
		printf("%s is not a palindrome string ",str1);
		
	}
	else
	{
		printf("%s is a palindrome",str1);
	}
	return 0;
	
	
}
