Structures

Example to use structure's member through pointer using malloc() function.

struct person{

 char name[20];

 int age;

 float marks;

}struct person *p;

int main()

{

      int num,i;

      printf("\nEnter no of persons to fill the details of\n");

      scanf("%d",&num);

      p = (struct p*) malloc(num * sizeof(struct person));

      for(i=0;i<num;i++)

      {

          scanf("%s%d%f",&(p+i)->name,&(p+i)->age,&(p+i)->marks);

       }

        for(i=0;i<num;i++)

      {

          scanf("\n%s\t%d\t%f\n\n",(p+i)->name,(p+i)->age,(p+i)->marks);

       }

return 0;

}
