else if(a%400==0)
cout<<”leap year”;
else
cout<<”not a leap year”;
getch();
}

9.       Write a program to check whether the number is odd or not. If the number is odd than check that it is divisible by 7 or not.

if(a%7==0)
cout<<”divisible by 7”;
}
cout<<”odd”;
else
cout<<”even”;
getch();
}

10.   Write a program to check whether the person has made profit or loss or no profit or loss. If the cost price and selling price is entered by user.
#include<iostream.h>
#include<conio.h>
void main()
{
int a;
cout<<”enter cost price”;
cin>>a;
cout<<”enter selling price”;
cin>>b;
if(a>b)
cout<<”loss”;
else
cout<<”profit”;
getch();
}

17. Write a program to find out the greatest angle of the triangle if the angles is given by the user
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int a,b,c,max;
cout<<"Enter the three angles of the triangle";
cin>>a>>b>>c;
max=a>b?(a>c?a:c):(b>c?b:c);
cout<<"The greatest angle of the triangle is<<" "<<max;
getch();
}

19. Write a program to find the bill for the telephone. The telephone charges Rs. 275 from all households and allows 100 units free. If the unit exceeds 100 Rs. 2.00 is charged for extra unit above 100 along with Rs. 275
#include<iostream.h>
#include<conio.h>
void main()
{
double u,b;
cout<<"enter units consumed";
cin>>u;
if(u<=100)
b=275;
else
b=275+(u-100)×2.00;
cout<<"final bill";
getch();
}

Distance  Amount
<=20        Rs. 200
>20 & <=50 Rs 200 + Rs 3 per extra kilometer above 20
>50 & <=100 Rs 500 + Rs 3 per extra kilometer above 50
>100        Rs 10 per kilometer
