I need help with my C$++$ program.

$-$I need to write a function$$divide$$that takes two integers as parameters and returns the result of their division. If the divisor is zero, throw an exception. Use the starter code below:

double divide$($int numerator, int denominator$)\{$

$//$ Your code here

$\}$

$-$i need to Write a function$$accessArray$$that takes an array and an index as parameters and returns the element at that index. If the index is out of bounds, throw an exception. Use the starter code below:

int accessArray$($int arr$[],$ int size, int index$)\{$

$//$ Your code here

$\}$

$-$ I need to Write a function$$nestedFunction$$that throws a$$CustomException$.$ In another function$$outerFunction$,$ call$$nestedFunction$$and catch the exception, then rethrow it$.$ Use the starter code below:

void nestedFunction$()\{$

$//$ Your code here $\}$

void outerFunction$()\{$

$//$ Your code here with nestedFunction$()$;

$\}$

$\}$

Example outputs of the functions:

Caught exception in outerFunction: Error in nestedFunction Caught rethrown exception in main: Error in nestedFunction

Enter numerator: $10$

Enter denominator: $0$

Error: Division by zero is not allowed.

Enter array size: $5$

Enter index to access: $10$

Error: Index out of bounds.
