Lab 11: Strings and Structures

Exercise 2                                                                                                                                             

Write a C++ program that maintain record of students. Student contains following details:

• ID       
• Name
• Department
• Email
• Phone no

Create a structure of student. Ask user to enter record for 5 students. Store those details in variables of students type. Print those records on screen.

Source Code:
#include<iostream>
#include<string>
using namespace std;
struct student{
string id,name,email,ph_no,depart;
}s[5];
int main()
{
for(int i=0;i<5;i++)
{
cout<<"================================="<<endl;
cout<<"Enter Data Of Student "<<i+1<<" : "<<endl;
cout<<"================================="<<endl;
cout<<"Enter Name : ";
getline(cin,s[i].name);
cout<<"Enter ID : ";
getline(cin,s[i].id);
cout<<"Enter Department : ";
getline(cin,s[i].depart);
cout<<"Enter Email : ";
getline(cin,s[i].email);
cout<<"Enter Phone no : ";
getline(cin,s[i].ph_no);
}
for(int i=0;i<5;i++)
{
cout<<"================================="<<endl;
cout<<"Data Of Student "<<i+1<<" : "<<endl;
cout<<"================================="<<endl;
cout<<"Name : "<<s[i].name<<endl;
cout<<"ID : "<<s[i].id<<endl;
cout<<"Department : "<<s[i].depart<<endl;
cout<<"Email : "<<s[i].email<<endl;
cout<<"Phone no : "<<s[i].ph_no<<endl;

}
return 0;


}

Exercise 3                                                                                                                                             

Write a C++ program to do the following:

-          Set up a structure/record to store products; each product has a name, a model number and a price.

-          Choose appropriate types for these fields.

-          Your program should contain a loop which allows entry via the keyboard of up to 10 products, to be stored in an array.

-          The loop can be stopped by entry of "quit" for the product name

-          Your program should include a function to display all the products details after the entry loop has finished.

Source Code:
#include<iostream>
#include<string>
using namespace std;
void display(int);
struct record{
string pro_name;
int model;
double price;
}r[10];
int main(){
int i=0;
do{
cout<<"================================="<<endl;
cout<<"Enter Data Of Product "<<i+1<<" : "<<endl;
cout<<"================================="<<endl;
cout<<"Or Type quit to terminate "<<endl;
cout<<"Enter Name : ";
cin>>r[i].pro_name;
if(r[i].pro_name=="quit")
{
break;
}
cout<<"Enter Model : ";
cin>>r[i].model;
cout<<"Enter Price : ";
    cin>>r[i].price;
    i++;
}
while(i<10);
display(i);
}
void display(int a)
{
for(int j=0;j<a;j++)
{
cout<<"================================="<<endl;
cout<<"Data Of Product "<<j+1<<" : "<<endl;
cout<<"================================="<<endl;
cout<<"Enter Name : "<<r[j].pro_name<<endl;
cout<<"Enter Model : "<<r[j].model<<endl;
cout<<"Price : "<<r[j].price<<endl;

}

}

Exercise 4                                                                                                                                             

Write  a  C++  program that compute Net Salary of Employee. Program contains two user defined functions empSalary() and display().

·         Create a structure of Employee that contains following data members:

o   EmployeeNumber, Name, BasicSalary, HouseAllowance, MedicalAllowance,Tax, GrossPay and NetSalary

·         Employeenumber,name and basicsalary must be taken input from the user.

·         empSalary() compute salary with given criteria

o   HouseAllowence =  10% of BasicSalary

o   Medical Allowence = 5% of Basic Salary

o   Tax = 4 % of Basic Salary

o   GrossSalary = Basic+HouseAllowence+MedicalAllowence

o   NetSalary = GrossSalary – Tax

·         display() for displaying details of Empolyee

Source Code:
#include<iostream>
#include<string.h>
using namespace std;
void emp_salary();
void display();
struct employe{
string name;
long int salary;
double house_all,medi_all,gross_salary,tax,net_salary;
int employee_id;
}e;
int main()
{
cout<<"Enter Employee ID : ";
cin>>e.employee_id;
cout<<"Enter Employee Name : ";
cin>>e.name;
cout<<"Enter Salary : ";
cin>>e.salary;
emp_salary();
display();
}
void emp_salary()
{
e.house_all=e.salary/100*10;
e.medi_all=e.salary/100*5;
e.gross_salary=e.salary+e.house_all+e.medi_all;
e.tax=e.salary/100*4;
e.net_salary=e.gross_salary-e.tax;

}
void display()
{
cout<<"House Allowence : "<<e.house_all<<endl;
cout<<"Medical Allowence : "<<e.medi_all<<endl;
cout<<"Gross Salary : "<<e.gross_salary<<endl;
cout<<"Tax : "<<e.tax<<endl;
cout<<"Net Salary : "<<e.net_salary<<endl;
