Swapping using MALLOC FUNCTION

 Q.) Write a C program for swapping of two values through malloc function.

#include<stdio.h>

#include<conio.h>

struct stud

{

char nam[30] ;

struct stud *next ;

} ;

struct stud *p,*q ;

int main( )

{

 p=(struct stud *)malloc(sizeof(struct stud)) ;

 q=(struct stud *)malloc(sizeof(struct stud)) ;

printf("Enter NAME p : ") ;

gets(p->nam) ;

            //fflush(stdin) ;

printf("Enter NAME q : ") ;

gets(q->nam) ;

p->next=q ;

q->next=p ;

printf("\n Name of P : %s", p->next->nam) ;

printf("\n Name of Q : %s", q->next->nam) ;

return 0 ;

}

        :: OUTPUT of above PROGRAM ::

Enter NAME p : BUNNY

Enter NAME q : SONU

Name of P : SONU

Name of Q : BUNNY
