C++ Practical Section 4

16. Write a Program to input salary and calculate bonus if salary<5000 then bonus is 500 else bonus is 1000.

Answer:

#include<iostream.h>
#include<conio.h>

Void main()
{
float salary,a,b;
clrscr();

cout<<"Enter the Salary:";
cin>>salary'

a=salary+500;
b=salary+1000;
if(salary<5000)
{
cout<<endl<<"Your salary is less than 5000";
cout<<endl<<"Bonus = 500\n";
cout<<endl<<"Total Salary="<<a;
}
else
{
cout<<endl<<"Your salary is greater than 5000";
cout<<endl<<"Bonus = 1000\n";
cout<<endl<<"Total Salary = "<<b;
}
getch();
}

17.  Write a Program to input salary calculate HRA,DA, Total Salary if Salary<5000 HRA is 5% of salary and DA is 7% of salary if salary between 5000-10000 HRA is 6% of salaryl and DA is 8% salary calculate total salary.

Answer:

#include<iostream.h>

#include<conio.h>

Void main()

{

float sal,hra1,hra2,da1,da2;

clrscr();

cout<<"Enter the Basic Salary:";

cin>>sal;

hra1=sal*5/100;

da1=sal*7/100;

hra2=sal*6/100;

da2=sal*8/100;

if(sal<5000)

{

cout<<endl<<"HRA= "<<hra1;

cout<<endl<<"DA= "<<da1;

cout<<endl<\n Total Salary="<<sal+hra1+da1;

}

else if(sal>5000<10000)

{

cout<<endl<<HRA= "<<hra2;

cout<<endl<<DA= "<<da2;

cout<<endl<<"\n Total Salary="<<sal+hr2+da2;

}

getch();

}

18. Write a Program to input two numbers and swap them using third variable.

Answer:

#include<iostream.h>

#include<conio.h>

Void main()

{

int a,b,t;

cout<<"Enter a,b";

cin>>a>>b;

cout<<a<<" "<<b<<;

t=a;

a=b;

b=t;

cout<<a<<" "<<b<<"\";

getch();

}

19. Write a Program to swap two number without using third variable.

Answer:

#include<iostream.h>

#include<conio.h>

Void main()

{

int a,b;

cout<<"Enter a,b";

cin>>a>>b;

cout<<a<<" "<<b<<;

a=a+b;

b=a-b;

a=a-b;

cout<<a<<" " <<b<<\n";

getch();

}

20.  Write a Program to input a number if the number is even then power 4 else power 5.

Answer:

#include<iostream.h>

#include<conio.h>

Void main()

{

cout<<"Enter the Number:";

cin>>num;

fourth = num*num*num*num;

five = num*num*num*num*num;

if(num%2 == 0)

{

cout<<"power fourth="<<fourth;

}

else

{

cout<<"power five="<<five;

}

getch();

}
