Finding sizeof structure without using sizeof operator


struct str
  int a;
  char d;
  int c;

int main()
  struct str a, b;
  struct str *pt, *qt;
  int size;

  pt = &a;
  qt = &b;

  size = (void*)pt-(void*)qt;

  printf("Size of struct = %d\n", size);

  return 0;

XOR ed value handling

In case encryption is done using xor, if you print/store these value in xml using %s then you may get wrong value; since there might be having non-printable chars,
to handle this kind of issue use character by character value to convert into equal integers using %d.
 enc_data[i] = src[i]^src[j];        // ENCRYPTING USING XOR

void xor_rev(char *src, int *enc_data)
  int i = 0, j, len;

  len = strlen(src);
  j = len - 1;

  for(i, j; i < len; ++i,--j)
    enc_data[i] = src[i]^src[j];        // ENCRYPTING USING XOR
  enc_data[i] = '\0';

void xor_test(int *enc_data, char *result)
  int x, y, len;

  len = strlen(src);

  printf("\nResult is \n");             //REMOVE LATER
  for(y = len-1, x = 0; y >=0 ; --y, ++x)
    printf("%c", result[x]);
