EX.NO:1 Function overloading

DATE:

AIM:

To write a c++ program to calculate volume of cube,cylinder,and rectangle using

function overloading.

ALGORITHM:

1. Start the program.2. Declare the prototypes for volume function to find volume of

cube,cylinder,rectangle.3. Get the input values such as side, length, breadth, height, and radius.4. Invoke volume function of cylinder by passing radius and height to find

volume of cylinder.

5. Invoke volume function of cube by passing side of cube to find volume ofcube.

6. Invoke volume function of Rectangle by passing length, breadth and height tofind volume of rectangle.

7. Print the volume of cube, cylinder and rectangle8. Stop the program.

Program

/* Function overloading*/

#include

#include

int volume(int);

double volume(double,int);

long volume(long,int,int);

int main()

{

int n,r,b,h1;

double h;

long l;

clrscr();

cout


6/78



return (3.14519*r*r*h);

}

long volume (long l,int b,int h)

{

return (l*b*h);

}

Sample Output:

Enter the side of cube: 6

Volume of Cube: 216

Enter the radius and height of cylinder: 5 50

Volume of Cylinder: 39314.875

Enter the length , breadth and height of Rectangle : 5 10 20

EX.NO:22 EXCEPTION HANDLING

DATE:

AIM:

To write java program to handle error or exception during runtime

ALGORITHM:

1. Start the program2. Define function divide () which perform division operation.3. Try to find with if there is any error occurs within divide function.4. If find catch the exception and throw it to exception handler to take necessary action.5. Stop the programPROGRAM:

/* Exception handling*/

class exceptionhandling

{


{

int d,a;

try

{

d=0;

a=42/d;

System.out.println("this will not be printed");

}

catch(ArithmeticException e)

{

System.out.println("division by zero");

}

System.out.println("after catch statement");

} }


71/78



Sample Output

division by zero

after catch statement

ResultThus above program executed and output verified.

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

String str;

System.out.println("Enter line of text");

System.out.println("enter stop to quit");

do

{

str=br.readLine();

System.out.println(str);

}

while(!str.equals("stop"));

}

}
