Program

#include<stdio.h>
struct student
{
   int usn;
   char name[20];
   float marks;
}s;
void main()
{	
	printf("Size of field USN is %d\n", sizeof(s.usn));
	printf("Size of field Name is %d\n", sizeof(s.name));
	printf("Size of field Marks is %d\n", sizeof(s.marks));
	printf("Size of structure is %d bytes\n", sizeof(s));
}

Output

Size of field USN is 4
Size of field Name is 20
Size of field Marks is 4
Size of structure is 28 bytes
