Question

.)   Write a program to implement the exception handling with multiple (at least 3) catch statements. Any type of exception may be thrown. Catch statements must display (cout) the type of exception thrown.

.)   Write a function which accepts an index and returns the corresponding element from an array. If the index is out of bounds, the function should throw an exception. Handle this exception in "main()".

(This is pretty open ended, so anything from a calculator or "what have you" will do. I do appreciate the help fully.)

Program 1:

#include<iostream>
using namespace std;

int main()
{
int a;
cout<<"Enter value of a : ";
cin>>a;

try
{
if(a==1)
{
throw a;
}
else if(a==2)
{
throw 'a';
}
else if(a==3)
{
throw a+1.5;
}
else
{
throw "";
}
}
catch(int x)
{
cout<<"Exception related to integer : "<<x;
}
catch(char x)
{
cout<<"Exception related character : "<<x;
}
catch(double x)
{
cout<<"Exception related to double : "<<x;
}
catch(char* x )
{
cout<<"Nothing is there : "<<x;
}
cout<<endl;
system("pause");
return 0;
