Palindrome program by using array C?

Answer 1

#include<stdio.h>

#include<math.h>

int main()

{

int num,a,b,c,d,y,k=0;

printf("Enter no.\n");

scanf("%d",&num);

y=num;

for(a=0;a<=num;a++)

{ c=pow(10,a);

d=num/c;

if (d>=1)

k=k+1;

else

break;}

printf(" an aaray of dimension %d" ,k);

int v1[k],v2[k];

int l=0,i,e,f;

for(i=k-1;i>=0;i--)

{

e=pow(10,i);

f=num/e;

v1[l]=f;

l++;

num=num%e;

}

int q,r,t=0,s=0;

q=y;

for(i=k-1;i>=0;i--)

{while(q!=0)

{

r=q%10;

v2[t]=r;

t++;

q=q/10;

}}

for (i=0;i<=k-1;i++)

{if(v1[i]==v2[i])

s++;}

if(s==k)

printf("the no.is palindrome\n");

else

printf("not a palindrome");

return 0;

}
