Exception handling

Write a C++ program to perform exception handling for Divide by zero Exception.

Program Algorithm:

Step 1: Include the header files

Step 2: Declare the variables a,b,c.

Step 3: Read the values a,b,c,.

Step 4: Inside the try block check the condition.

a. if(a-b!=0) then calculate the value of d and display.

b. otherwise throw the exception.

Step 5: Catch the exception and display the appropriate message.

Program Code in C++:

#include<iostream.h>

#include<conio.h>

void main()

{

int a,b,c;

float d;

clrscr();

cout<<"Enter the value of a:";

cin>>a;

cout<<"Enter the value of b:";

cin>>b;

cout<<"Enter the value of c:";

cin>>c;

try

{

if((a-b)!=0)

{

d=c/(a-b);

cout<<"Result is:"<<d;

}

else

{

throw(a-b);

}

}

catch(int i)

{

cout<<"Answer is infinite because a-b is:"<<i;

}

getch();

}

Program Output:

Enter the value for a: 20

Enter the value for b: 20

Enter the value for c: 40

Answer is infinite because a-b is: 0
