C Program for length of string without using in-built and check for palindrome

C program to find the length of a given string without using in-built

function. Also check for palindrome.

#include<stdio .h="">

#include<conio .h="">

void main()

{

 int m,n,i,j,l;

 char a[50],*p;

 clrscr();

 printf("Enter String to check palindrome or not\n");

 gets(a);

 p=a;l=0;

 while(*p!='\0')

 {

  l++;

  p++;

 }

 p--;

 printf("\nLength Of String Is == %d\n",l);

 for(i=0;i&lt;=l/2;i++,p--)

 {

  if(a[i]!=*p)

  {

   printf("\n\nString is not Palindrome");

   break;

  }

 }

 if(a[i]==*p)

 printf("\n\nString Is Palindrome");

 getch();

}

/*Output

Enter String to check palindrome or not

123321

Length Of String Is == 6

String Is Palindrome
