Calculate Size of Structure
Size of Structure can be calculated as -

1. By observation
2. By Using sizeof Operator
3. Without using Sizeof Operator

Way 1 : Calculate by adding Individual Sizes

struct Book
{
int pages;
char name[10];
char author[10];
float price;  
}b1;

Calculating Size of Structure :
= size of 'Pages' + size of 'Name' + size of 'Author' + size of 'Price'
= 2 + 10 * 1 + 10 * 1 + 4
= 2 + 10 + 10 + 4
= 26
Note :

1. Add all the individual Size of Each Structure Member .
2. Character array requires Memory Equivalent to  (No_of_elements * Sizeof(char))
3. Float , Integer requires 4,2 bytes respectively in Case of Borland CC++ 3.0

printf("Size of Structure : %d",sizeof(b1));
