Pointer to Structure

1. Pointer to Structure

2. Pointer to Structure • Structure variable can be access using pointers • int a=10,*p; • Here p is an integer type pointer variable, p can hold the address of an integer(a) iep=&a; in order to access the content of a  *p ie ‘a’ can be access using the pointer variable p • Like that a structure variable can be access using a pointer variable

3. Pointer to Structure • let • struct student • { • char name[20]; • int m1,m2,m3,total • }; struct student s , *p; Now ‘s’ is the variable of type struct student ‘p’ is a pointer variable of type struct student Since p and s are same type, p can store the address of the variable s Iep=&s; Now the content of p is address of s

4. Pointer to Structure • The structure variable s can be access using p • With the help of point to operator (->) • ie • p->name equalant to s.name • p->m1 equalant to s.m1 • p->m2 equalant to s.m2 • p->m3 equalant to s.m3 • p->total equalant to s.total

5. Pointer to Structure • void main() • { • struct check • { • int a; • char c[20]; • }; • struct check s,*p; • p=&s; • scanf("%d%s",&p->a,p->c); • printf("%d %s",p->a,p->c); • getch(); • }
