problem with structures

[baffleddreams]

in structures can we swap two structure variables as such?like for example:
say i create a structure called book and i want to arrange the books in ascending order depending on the book name.i.e.,the contents like price and the number of pages should get swapped along with the name:

struct book
{
char name[10];
char author[10];
int pages;
float price;
}b[20];

here i am asking if we can swap b[1] as such along with its contents with b[3],instead of going variable by variable: b[1].name with b[3].name

When in doubt, try it and see.

#include <stdio.h>

struct book{
  int x;
} a[3];

int main(){
  a[0].x = 0;
  a[1].x = 1;

  a[0] = a[1];
  printf("a[0].x: %d\na[1].x: %d\n", a[0].x, a[1].x);

  return 0;
}

OUTPUT:

$ ~/a.out
a[0].x: 1
a[1].x: 1

Yep. You can.

struct book {
  char name[20];
  char author[20];
  int pages;
  float price;
  } 

struct book books[200];
struct book temp.

// swap
temp = books[35];
books[35] = books[131];
books[131] =  temp;
