Q13.Write a program that will take three values a,b and c and print the roots, if real, of the quadratic equation ax*X+b*x+c=0.Sample input 1:(a=1, b=1,c=-6 the output should be "Roots of the equation are 2 and -3").Sample input 2(if the input is a=1,b=0,c=9, the output should be "Sorry the roots are not real.")
#include<iostream.h>
#include<conio.h>
#include<math.h>
#include<iomanip.h>
void main()
{
clrscr();
int a,b,c,d,e;
double f,x1,x2;
cout<<"enter value of a";
cin>>a;
cout<<"enter value of b";
cin>>b;
cout<<"enter value of c";

cout<<"not a eq A cannot be zero"<<endl;

Q14.Write a program that inputs the salary of an employee from the user.It deducts the income tax from the salary on the following basis:
. 20% income tax if the salary is above Rs.30000.
.15% income tax if the salary is between Rs.20000 and Rs.30000
.10% income if the salary is below Rs.20000.
The program finally displays salary,income tax and net salary.
#include<iostream.h>
#include<conio.h>
#include<iomanip.h>
void main()
{
int sal;
float net,in;
clrscr();
cout<<"enter salary:";
cin>>sal;
if(sal>30000)
{
in=(20/100);
net=sal-(sal*in);
cout<<"net salary is:"<<setprecision(2)<<net;
cout<<"and income tax is:"<<in;
}
else if(sal>20000&&sal<30000)
{
in=15/100;
net=sal-(sal*in);
cout<<"net salary is:"<<net<<"income tax is:"<<in;;
}
else
sal=net;
cout<<"net salary is"<<net;
getch();
}
Q15.Write a program that inputs year and month.It displays the number of days in the month of the year entered by the user.For example,if the user enters 2010 in year and 3 in month, the program should display"March 2010 has 31 days".
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int year,month,number_of_days_in_month=0;
cout<<"enter a year\n";
cin>>year;
cout<<"enter a month in the year";
cin>>month;
switch(month)
{
case1:
cout<<"january"<<year;
number_of_days_in_month=31;
break;
case2:
cout<<"feburay"<<year;
if(year%400==0||(year%4==0&& year%100!=0))
number_of_days_in_month=29;
else
number_of_days_in_month=28;
break;
case 3:
cout<<"march"<<year;
number_of_days_in_month=31;
break;
case 4:
cout<<"april"<<year;
number_of_days_in_month=30;

number_of_days_in_month=31;
case 6:
cout<<"june"<<year;
number_of_days_in_month=30;
break;
case 7:
cout<<"july"<<year;
number_of_days_in_month=31;
break;
case 8:
cout<<"august"<<year;
number_of_days_in_month=31;
break;
case 9:
cout<<"september"<<year;
number_of_days_in_month=30;
break;
case 10:
cout<<"october"<<year;
number_of_days_in_month=31;

case 11:
cout<<"november"<<year;
number_of_days_in_month=30;
break;
case 12:
cout<<"december"<<year;
number_of_days_in_month=31;

Q16.Write a program that displays the following menu for a parking area:
. M =Motorcycle
. C =Car
. B =Bus
The program inputs the type of vehicle and number of day to park the vehicle.It finally displays the total charges for the parking according to the following:
.Motorcycle Rs. 10 per day
.Car Rs.20 per day
.Bus Rs.30 per day
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int days;
char p;
cout<<"M=motorcycle\n";
cout<<"C=car\n";
cout<<"B=bus\n";
cout<<"enter parking choice:";
cin>>p;
cout<<"how many days to park?";
cin>>days;
switch(p)
{
case'M':
case'm':
cout<<"parking charges: Rs."<<days*10;
break;
case 'C':
case 'c':
cout<<"parking charges: Rs."<<days*20;
break;
case 'B':
case 'b':
cout<<"parking charges:Rs."<<days*30;
break;
default:
cout<<"invalid parking choice";
}
getch();
}
Q17.Write a program that inputs a value and type of conversion.The program should then display the output after conversion.The program should include the following conversions.
. 1cm = .394 inches
. 1 liter = .264 gallons
. 1 kilometer =.622 nmiles
. 1 kilogram = 2.2 pounds
Make sure that the program accepts only valid choices for the type of conversion...
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
float value;
char conversion;
cout<<"enter the value"<<endl;
cin>>value;
cout<<"enter the type of conversion"<<endl;
cout<<"I inches"<<endl;
cout<<"G gallons"<<endl;
cout<<"M miles"<<endl;
cout<<"p pounds"<<endl;
cin>>conversion;
switch(conversion)
{
case 'I':
case 'i':
cout<<value*.394<<endl;
break;
case 'G':
case 'g':
cout<<value*.264<<endl;
break;
case 'M':
case 'm':
cout<<value*.622<<endl;
case 'P':
case 'p':
cout<<value*2.2<<endl;
break;
default:
cout<<"illegal input"<<endl;
break;
}
getch();
