1. Write
a program to define structure with tag state with fields state name, number of
districts and total population. Read and display the data.
#include<stdio.h>
struct state
{
char name[10];
int n_dist;
long population;
};
void main()
{
struct state s1;
printf("\n enter data of state: name, no of district and
population");
scanf("%s%d%d",s1.name,&s1.n_dist,&s1.population);
printf("\n The Details are as under\n");
printf("\n name is %s\n No of dist
are %d \n population is
%d",s1.name,s1.n_dist,s1.population );
}
2.
Write a program to create a list of books details. The details of a book
include title, author, publisher, publishing year, number of pages, and price.
[Do it yourself]
3.
Define a structure called Item with members: Item_code, Item_name, Price.
Create an array of five Items. Create a function which accepts the Item array
and modifies each element with an increase of 10% in the price.
#include<stdio.h>
#include<conio.h>
struct item
{
int code;
char name[10];
int price;
};
void inc(struct item it[],int x);
void main()

}
inc(it,5);
}
void inc(struct item it[],int x)
{
int i;
for(i=0;i<5;i++)
{
it[i].price += it[i].price*0.1;
printf("\n %d %s %d",
it[i].code,it[i].name,it[i].price);
} }
4.
Define a structure to represent a date. Use your structures that accept two
different dates in the format mm dd of the same year. Write a C program to
display the month names of both dates.
#include<stdio.h>
#include<conio.h>
struct date
{
int mm;
int dd;
int year;
};
void main()
{
struct date d1,d2;
label:
printf("\n Enter first mm,dd,year");

printf("\n Valid Dates");
printf("\n %d",d1.mm);
printf("\n %d",d2.mm);
}
}
5.
Define a structure that can describe a Hotel. It should have members that

} } }
6.
Write a program to accept records of different states using array of
structures. The structure should contain char state and number of int
engineering colleges, int medical colleges, int management colleges and int
universities. Calculate total colleges and display the state, which is having
highest number of colleges.
#include<stdio.h>
#include<conio.h>
struct state
{
char sta[10];
int eng_clg;
int med_clg;
int mgmt_clg;
int uni;
int t_clg;

struct state s1[5];
int i,max=0;
printf("\n Enter Data");
for(i=0;i<5;i++)
{
scanf("%s%d%d%d%d",s1[i].sta,&s1[i].eng_clg,&s1[i].med_clg,
&s1[i].mgmt_clg,&s1[i].uni);
s1[i].t_clg=s1[i].eng_clg+s1[i].med_clg+s1[i].mgmt_clg+s1[i].uni;
if(max<s1[i].t_clg)
max=s1[i].t_clg;
}
for(i=0;i<5;i++)
{
if(max==s1[i].t_clg)
{
printf("The state which is having highest clgs is
%s",s1[i].sta);
} } }
7.
Define a structure by name time with members seconds, minutes and hours of int
type. A variable of the structure would thus represent time. If time1 and time2
are two variables of the structure type, write a program to find the difference
of two times using a function.
#include<stdio.h>
struct st_time
{
int sec;
int min;
int hr;
};
void diff(struct st_time,struct st_time);
void main()
{
struct st_time t1,t2;
printf("\n Enter second,minute and Hour for the first
time");
scanf("%d%d%d", &t1.sec,
&t1.min,&t1.hr);
printf("\n Enter second,minute and Hour for the Second
time");
scanf("%d%d%d", &t2.sec,
&t2.min,&t2.hr);
diff(t1,t2);
}
void diff(struct st_time t1, struct st_time t2)
{
printf("\n Difference between two time is %d:%d:%d",
t1.sec-t2.sec,t1.min-t2.min,t1.hr-t2.hr);
}
8.
