Programs Using Structure

Declare a structure named “library” which will contains data members: bookno, bookname, price, publication. Read and print the structure.

#include<stdio.h>
#include<conio.h>
struct library
{
   int bookno;
   char bookname[20];
   float price;
   char publication[20];
};
void main()
{
   struct library l1;
   clrscr();
   printf(“Enter Book Number:”);
   scanf(“%d”,&l1.bookno);
   printf(“Enter Book Name:”);
   scanf(“%s”,l1.bookname);
   printf(“Enter Book Price:”);
   scanf(“%f”,&l1.price);
   printf(“Enter Publication:”);
   scanf(“%s”,l1.publication);
   printf(“Book Number:%d\n”,l1.bookno);
   printf(“Book Name:%s\n”,l1.bookname);
   printf(“Book Price:%f\n”,l1.price);
   printf(“Publication:%s\n”,l1.publication);
getch();
}

Output

Create a structure named student that accepts student rollno, name, gender and marks of 3 subjects. Find total of marks and percentage. Create an array of structure variable to enter information for three students.

#include<stdio.h>
#include<conio.h>
struct student
{
   char name[20];
   int regno;
   char gender[10];
   int mark1,mark2,mark3,total;
   float per;
};
void main()
{
   struct student s[3];
   int i;
   clrscr();
   for(i=0;i<3;i++)
   {
printf("Enter Roll Number:");
scanf("%d",&s[i].regno);
printf("Enter Name:");
scanf("%s",s[i].name);
printf("Enter gender:");
scanf("%s",s[i].gender);
printf("Enter mark1:");
scanf("%d",&s[i].mark1);
printf("Enter mark2:");
scanf("%d",&s[i].mark2);
printf("Enter mark3:");
scanf("%d",&s[i].mark3);
s[i].total=s[i].mark1+s[i].mark1+s[i].mark1;
s[i].per = (float)s[i].total/3;
}
printf("*****Student Information*******\n");
for(i=0;i<3;i++)
{
   printf("Roll Number:%d\n",s[i].regno);
   printf("Name:%s\n",s[i].name);
   printf("Gender:%s\n",s[i].gender);
printf("Mark1:%d\n",s[i].mark1);
   printf("Mark2:%d\n",s[i].mark2);
   printf("Mark3:%d\n",s[i].mark3);
   printf("Total:%d\n",s[i].total);
   printf("Percentage:%f\n",s[i].per);
}
getch();
}
