C Structure
Giving values to members
/* Example program for using a structure*/
#include <stdio.h>
void main()
{
int id_no;
char name[20];
char address[20];
char combination[3];
int age;
}newstudent;
printf(“Enter the student information”);
printf(“Now Enter the student id_no”);
scanf(“%d”,&newstudent.id_no);
printf(“Enter the name of the student”);
scanf(“%s”,&new student.name);
printf(“Enter the address of the student”);
scanf(“%s”,&new student.address);
printf(“Enter the cmbination of the student”);
scanf(“%d”,&new student.combination);
printf(“Enter the age of the student”);
scanf(“%d”,&new student.age);
printf(“Student information\n”);
printf(“student id_number=%d\n”,newstudent.id_no);
printf(“student name=%s\n”,newstudent.name);
printf(“student Address=%s\n”,newstudent.address);
printf(“students combination=%s\n”,newstudent.combination);
printf(“Age of student=%d\n”,newstudent.age);
}
Giving values to members
As mentioned earlier the members themselves are not variables they should be linked to structure variables in order to make them meaningful members. The link between a member and a variable is established using the member operator ‘.’ Which is known as dot operator or period operator. For example:
Book1.price
Is the variable representing the price of book1 and can be treated like any other ordinary variable. We can use scanf statement to assign values like
scanf(“%s”,book1.file); scanf(“%d”,& book1.pages);
