More About Catch in C++

In the code, a float value 1.8f is thrown using the throw statement. The try block is used to catch the thrown exception. There are three catch blocks provided to catch exceptions of different types:

The first catch block catches int type exception. However, since the exception thrown is of type float, this block will not execute.
The second catch block catches float type exception. Since the exception thrown is of type float, this block will execute and the output will be "Float Catch : 1.8".
The third catch block is a catch-all block and will execute if none of the previous catch blocks match the type of the thrown exception. In this case, this block will not execute.

After the catch blocks, "End" will be printed to the console.

Source Code

#include<iostream>
using namespace std;
int main()
{
    try
    {
        throw 1.8f;
    }
    catch(int e)
    {
        cout<<"Integer Catch : "<<e<<endl;
    }
    catch(float e)
    {
        cout<<"Float Catch : "<<e<<endl;
    }
    catch(...)
    {
        cout<<"All Catch : "<<endl;
    }
    cout<<"End";
    return 0;
}
