#include<conio.h>
#include<stdio.h>
struct employee
{
int empno;
char name[25];
int sly;
}emp;
void main()
{
cout<<”enter the employee number”;
cin>>emp.empno;
cout<<”enter the employee name”;
gets(emp.name);
cout<<”enter salary”;
cin>>emp.sly;
cout<<”\nempioyee details”;

 #include<iostream.h>
#include<conio.h>
#include<studio.h>
struct student
{
int rollno;
char name[25];
float per;
}stu[5];
void main()

int i;
for(i=0;i<5;i++)
{
cout<<”Enter the roll no”;
cin>>stu[i].rollno;
cout<<”Enter the name”;

cout<<”Enter the percentage”;
cin>>stu[i].per;
}
clrscr();
cout<<”Student details”;
for(i=0;i<5;i++)

#include<conio.h>
#include<studio.h>
struct product
{
int no;
char name[25];
int price;
}
pro[10];
void main;
{
float max=0;
int i,key;
for(i=0;i<10;i++)
{
cout<<”Enter product number”;
cin>>pro[i].pno;
cout<<”Enter product name”;
gets(pro[i].pname);
cout<<”Enter product price”;
cin>>pro[i].price;
}
if(pro[i].price>max)
{
max=pro[i].price;
key=i;
}
}
clrscr();
cout<<”The detail of products with maximum price”;
cout<<”/nproduct no.”pro[key].pno;

Write a program to input name roll no and date of birth of three students from the user and display these information on the screen. The name should be further divided into first name and last name and stored in a structure. Date of birth is also divided into the date, month and year and stored in another structure to design the program.

#include<iostream.h>
#include<conio.h>
#include<studio.h>
struct name details
{
char fname[25];
char lname[25];
};
struct date of birth
{
int dd;
int mm;
int yy;
};
struct student
{
name details n;
int rno;
date of birth dob;
}s[3];
void main()
{
int i;
for(i=0;i<3;i++)
{
clrscr();
cout<<”Enter name of student”;
cin>>s[i].n.fname>>s[i].n.lname;
cout<<”Enter roll no”;
cin>>s[i].rno;
cout<<”date of birth”;
cin>>s[i].dob.dd>>s[i].dob.mm>>s[i].dob.yy;
}
clrscr();
cout<<”student’s details”;
for(i=0;i<3;i++)
{
cout<<”/nstudent name=”<<s[i].n./name<<””<<s[i].n.lname;
cout<<”/nstudent roll number=”<<s[i].rno;
cout<<”/nstudent date of birth”; cout<<s[i].dob.dd<<”/”<<s[i].dob.mm<<”/”<<s[i].dob.yy;
}
getch();
}
output
student name=dolly
student roll number=2
student date of birth23/9/2000
student name=riya
student roll number=5
student date of birth3/9/2001
student name=betty
student roll number=7
student date of birth7/3/2000






Write a program to input name and marks of three subjects from user and print name with average marks.

#include<iostream.h>
#include<conio.h>
#include<stdio.h>
struct  marks
{
int sub1;
int  sub2;
int sub3;
}
struct  student
{
char name[50];
marks mk;
}s;
void main()
{
float avg;
cout<<”enter the name”;
gets(s.name);
cout<<”enter the marks”;
cout<<”sub1”;
cin>>s.mk.sub1;
cout<<”sub2”;
cin>>s.mk.sub2;
cout<<”sub3”;
cin>>s.mk.sub3;
avg=(s.mk.sub1+s.mk.sub2+s.mk.sub3)/3;
clrscr();
cout<<”name=”<<s.name;
cout<<”average marks=”<<avg;
getch();
}
output
name=riya
average marks=78
