-------------------------------------------------------------------------------------------------------------------
ans:-
q1.)Write a program considering user defined variable distance with members:feet and inch.
Calculate the sum two different distances.
ans:
code:
#include<stdio.h> //header file
struct distance //struct tag{
int inch; //first member
int feet; //second member
}d1,d2,tot; //variables to access members
int main()
{
printf("enter first inch and feet\n");
scanf("%d%d",&d1.inch,&d1.feet); //gets data
printf("enter first inch and feet\n");
scanf("%d%d",&d2.inch,&d2.feet); //gets data
tot.inch=(d1.inch+d2.inch)%12; //returns left part of inch
tot.feet=d1.feet+d2.feet+(d1.inch+d2.inch)/12;//returns total feet
printf("total inch=%d feet=%d\n",tot.inch,tot.feet);//prints result
return 0;
}
q2)Write a program considering user defined variable time with members:hh,mm and ss.
Calculate the sum two different times.
ans:
code:
//program to add two times given in hrs,mm and ss using struct
#include <stdio.h>
struct timeaddition
{
int hrs;
int mm;
int ss;
}time1,time2,ttime;
int main()
{
int totalmm;
printf("enter first time in hrs,minutes and seconds\n");
scanf("%d%d%d",&time1.hrs,&time1.mm,&time1.ss);
printf("enter second time in hrs,minutes and seconds\n");
scanf("%d%d%d",&time2.hrs,&time2.mm,&time2.ss);
totalmm=time1.mm+time2.mm+(time1.ss+time2.ss)/60;
ttime.ss=(time1.ss+time2.ss)%60;
ttime.mm=totalmm%60;
ttime.hrs=time1.hrs+time2.hrs+totalmm/60;
printf("total hrs=%d minutes=%d and seconds=%d\n",ttime.hrs,ttime.mm,ttime.ss);
return 0;
}
q3)Consider structure student with members:sid,name and height. Write a program that takes maximum 100 records,rearrange the records in ascending order on the basis of height and prints them.
ans:
code:
//program to sort records using struct from a to z
#include<stdio.h>
#include<conio.h>
struct detail
{
int sid;
char sname[100];
int sheight;
}var[100],temp;
int main()
{
int i,j,n;
printf("now enter records of students\n");
for(i=0;i<100;i++)
{
printf("enter student's id.\n");
scanf("%d",&var[i].sid);
printf("enter student's height\n");
scanf("%d",&var[i].sheight);
printf("enter student's name\n");
scanf("%s",var[i].sname);
}
printf("now sorting from a to z on the basis of height\n");
for(i=0;i<100;i++)
{
for(j=i+1;j<100;j++)
{
if((var[i].sheight>var[j].sheight)
{
temp=var[i];
var[i]=var[j];
var[j]=temp;
}
}
}
printf("sorted data (from a to z i.e. ascending order )on the basis of height are:\n:");
for(i=0;i<100;i++)
{
printf("student's id=%d, student's height=%d, student name=%s, \n",var[i].sid,var[i].sheight,var[i].sname);
}
getch();
return 0;
}
q4)Write a program that takes empid,name and salary of 100 employees and search a particular employee's record in the array of structure of the basis of empid.Also find the position of the record.
ans:
code:
// program to search data in given detail of some employees
#include <stdio.h>
struct data
{
int empid;
char empname[80];
float empsalary;
}access[100];
int main()
{
int n,i,loc=0; //variable declaration
int empsearch;
printf("enter records\n");
for(i=0;i<100;i++)
{
puts("enter employee id\n");
scanf("%d",&access[i].empid);
puts("enter employee name \n");
scanf("%s",access[i].empname);
puts("enter employee salary\n");
scanf("%f",&access[i].empsalary);
}
printf("enter emp id to be searched \n");
scanf("%d",&empsearch); //data input to be searched
for(i=0;i<100;i++)
{
if(access[i].empid==empsearch)//data comparison
{
loc=1;
break; //terminating the loop
}
}
if(loc==1)
{
printf("data found and location=%d",i);//printing the location of data
printf("data is,empid=%d,\tempname=%s,\temp salary=%f\n",access[i].empid,access[i].empname,access[i].empsalary);
}
else
{
printf("not found\n");

char empname[80];
char emppost[80];
float empsalary;
