Rewrite the following using nested switch construct.

#include<iostream>

using namespace std; 

int main() 

{ 

int a,b;

cout<<"Enter value for a and b";

cin>>a>>b;

if(b==0)

    cout<<"Divide by zero error";

else

    if(a==0)

    cout<<"The result is zero";

else

   cout<<"The result is "<<(float)a/b;

}

#include<iostream>

using namespace std; 

int main() 

{ 

int a,b;

cout<<"Enter value for a and b";

cin>>a>>b;

switch(b)

{

case 0 : cout<<"Divide by zero error";

break;

default:

switch(a)

{

case 0:cout<<"The result is zero";

break;

default:

cout<<"The result is "<<(float)a/b;

}

}

}
