To provide manipulation in a single bit of data or into the multiple bits we will use the things for these bit manipulation.

struct {
   unsigned int widthValidated;
   unsigned int heightValidated;
} status;

This will give you the total size occupied by the data type included in this structure as a combine.

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

/* define simple structure */
struct {
   unsigned int widthValidated;
   unsigned int heightValidated;
} status1;

/* define a structure with bit fields */
struct {
   unsigned int widthValidated : 1;
   unsigned int heightValidated : 1;
} status2;
 
int main( ) {

   printf( "Memory size occupied by status1 : %d\n", sizeof(status1));
   printf( "Memory size occupied by status2 : %d\n", sizeof(status2));

   return 0;
}
