Question

In addition to including an exceptions library, you can also create exceptions by using the throw keyword.

(1pt) Create a function called int throwsInt() that will throw an integer

(1pt) Create a function called double throwsDouble() that will throw a double

(2pt) Using try/catch statements, expand the code stubs to call each function in it's own try block, and catch and report the thrown value.

Provided code:

#include <iostream>

using namespace std;

int throwsInt();

double throwsDouble();

int main() {
cout << "about to run throwsInt()" << endl;

try {
int val = throwsInt();
cout << "val: " << val << endl;
}
catch (int i) {
cout << "Caught integer: " << i << endl;
}

cout << "about to run throwsDouble()" << endl;

// Build your try/catch based on the example above!
}

int throwsInt() {
//implement this function here
}

double throwsDouble() {
//implement this function here
}

Answer 1

#include <iostream>
#include <exception>

using namespace std;

int throwsInt();
double throwsDouble();

int main()
{
cout << "about to run throwsInt()" << endl;
  
try
{
//method calling
int val = throwsInt();
  
//display value
cout << "val: " << val << endl;
}
catch (int i)
{
cout << "Caught integer: " << i << endl;
}
  
cout << "about to run throwsDouble()" << endl;
try
{
//method calling
double val = throwsDouble();
  
//display value
cout << "val: " << val << endl;
}
catch (double i)
{
cout << "Caught integer: " << i << endl;
}
}

int throwsInt()
{
//return statement
return 10;
}

double throwsDouble()
{
//return statement
return 20.00;
}
