PLEASE C++ ONLY

Redo programming exercise 8 of chapter 4 so that your program handles exceptions such as division by zero and invalid input. Write a program that mimics a calculator. The program should take as input two integers and the operation to be performed. It should then output the numbers, the operator, and the result. (For division, if the denominator is zero, output an appropriate message). Some sample outputs follow:

3 + 4 = 7

13 * 5 = 65

REFERENCE CODE

using namespace std;

int main()

{

inta, b;

char ch;

try

{

cout << "Enter two numbers: ";

cin >> a >> b;

cout <

if (b==0)

throw b;

cout << " 1. Addition 2.Substraction 3. Multiply 4. Division 5.Modulus" <

cout << " Enter your choice (+ or - or * or %): ";

cin >> ch;

switch (ch)

{

case'1': cout << " Add="<

break;

case'2': cout << " Sub="<

break;

case'3': cout << " Mul="<

break;

case'4': cout << " Div="<

break;

case'5': cout << " Mod="<

break;

default: throw ch;

}

}

catch(int b)

{

cout<"<

}

catch(char ch)

{

cout<"<

}

system("pause")

}

Explanation / Answer

#include <iostream>
using namespace std;
int main()
{
int a, b;
char ch;
try {
cout << "Enter two numbers: ";
cin >> a >> b;
if (b == 0) throw b;
cout << " 1.Addition 2.Substraction 3.Multiply 4.Division 5.Modulus ";
cout << " Enter your choice (+ or - or * or %): ";
cin >> ch;
switch (ch) {
case '1':
cout << a << " + " << b << " = " << a+b;
break;
case '2':
cout << a << " - " << b << " = " << a-b;
break;
case '3':
cout << a << " * " << b << " = " << a*b;
break;
case '4':
cout << a << " / " << b << " = " << a/b;
break;
case '5':
cout << a << " % " << b << " = " << a%b;
break;
default:
throw ch;
}
}
catch (int b) {
cout << "Denominator cannot be zero " << endl;
}
catch (char ch) {
cout << "Invalid selection" << endl;
}
}
/*
sample output

Enter two numbers: 3 4
1.Addition
2.Substraction
3.Multiply
4.Division
5.Modulus
Enter your choice (+ or - or * or %): 3
3 * 4 = 12
