PALINDROME CHECKING

  CHECK THE CHARACTERS  ARE PALINFROME OR NOT 

🤔

what  palindrome ?

 word, number, phrase, or other sequence of symbols that reads the same backwards as forwards.peaples using lots of words in the palindrome without realizing it.: A man, a plan, a canal: Panama! =>is the famous palindrome sentence.

   

We can find this palindrome in places like in numbers,words,names , sequence ....

Now write a code to find the input is palindrome or not .

-----------------------------------------------------------------------------------------------------------------------------

#include<stdio.h>

#include<string.h>//  In this program we use the strlen() function .so we need to include this                                 header file💡

void main()

{

int len,i,count=0,rev=0;

char c[20];

while(rev==0)

{

printf("enter the string \t:");

scanf("%s",&c);

len=strlen(c);     // strlen()this function can find the length of the character.{ hai=3}three is                                     the length of the character hai.

printf("total length is:%d\n",len);

for (i=0;i<len;++i)

{

if(c[i]==c[len-i-1])// len-i-1  = ex {  len =5,  5-0-1=4, again the loop will decrement the                                              value.                        

                                                                             how the looping will pros

{                                                                  ex len=5;

printf("palindrome\n");                            c[0]==c[4]

                                                                  c[1]==c[3]

}                                                                          c[2]==c[2]

else                                                                       c[3]==c[1]

                                                                                                c[4]==c[0]

{

printf("Not a palindrome\n");

}

}

printf("anything want to check again : 0=NO \t 1=YES\n");

scanf("%d",&rev);

}

}

this string palindrome will take the input value as a array conversion .and check the value from 0th array to last array.2nd array to 2nd from last in this format of  checking was perform in there.
