Question

12.5 Program: Divide by Zero (C++)

This program will test exception handling during division.

The user will enter 2 numbers and attempt to divide (in a try block) the 1st number by the 2nd number.

The program will provide for 2 different catch statements:

Division by zero - denominator is zero

Division results in a negative number

The user should be prompted with Enter 2 numbers:

For input of 7 and 0 the output should be Exception: Division by zero

For input of 7 and 2 the output should be a/b = 3.5

For input of 7 and -2 the output should be Exception: Division is negative

Explanation / Answer

DivideByZero.cpp

#include<iostream>
using namespace std;

int main()
{
   int a,b; // declarations of integer variables
   float c,d; // declarations of float variables
   try // try block to check the numbers whether throw exception or not
   {
       cout<<"enter the two numbers"<<endl;
       cin>>a>>b; // reading two integers
       if(b>0) // contion tocheck denominotor greter than 0
       {
           c=(float)a/b; // casting integer value to float value
           cout<<"a/b="<<c<<endl;
       }
       else if(b==0)
       {
           throw b;// raising exception
       }
       else if(b<0)
       {
       d=a/b;
       throw d;
       }
       }
       catch(int) // catching divide by zero exception
       {
           cout<<"Division by zero"<<endl;
       }

       catch(float j) // catching division by negative exception
       {
           cout<<"Division by Negative"<<endl;
       }
   return 0;
}

output:

**************************************
Test Case1:

sh-4.2$g++ DivideByZero.cpp -Wall -o a.out
enter the two numbers 7 0   
Division by zero
***************************************
Test Case2:

sh-4.2$ g++ DivideByZero.cpp -Wall -o a.out
enter the two numbers   
7 -2
Division by Negative
****************************************
Test Case3:

sh-4.2$ g++ DivideByZero.cpp -Wall -o a.out
enter the two numbers 7 2   
a/b=3.5
