$2.$ Consider the following C$++$ skeletal program:

class Big $\{$

int i;

float f; void fun$1()$ throw int $\{$

$...$ try $\{...$ throw i; $...$

throw f; $...\}$ catch$($float$)\{...\}...$

$\}$

$\}$

class Small $\{$

int j;

float g; void fun$2()$ throw float $\{$

$...$ try $\{...$ try $\{$

Big.fun$1()$; $...$

throw j; $...$ throw g; $...\}$ catch$($int$)\{...\}...\}$

catch$($float$)\{...\}\}$

$\}$

In each of the four throw statements, where is the exception handled? Note that fun$1$ is called from fun$2$ in class Small.
