Q$1)$Write a C$++$ program that can read data from an input file $($provided at the bottom$)$ into a

one dimensional array $($don$$t use vector$)$ and perform the following functions:

$1)$ A function to check if a certain integer exists in the array if the number is present return the

index where the number is present.

$2)$ A function that can modify the value of an integer when called with the index of the integer in

the array and return the new value and old value back to the user.

$3)$ A function that adds a new integer to the end of the array

$4)$ A function which intakes an index of an array and replaces the value with either $0$ or removes

the integer altogether.

Q$2)$ A way to indicate an error, especially if there are several possible errors in code, is

through the use of exceptions. Exceptions are used to signal that an error has occurred. You can insert

code in your program that throws an exception when a particular kind of error occurs. An exception

handler allows the user to catch or handle the exception. To avoid uncaught exceptions, you write a try

block that can throw an exception and follow it with a catch block that catches the exception and

handles it$.$ Using the array code from question $1$ perform the following:

$1)$ Add a try and catch blocks to the user inputs for the following functions from question $1$:

$$ A function that can modify the value of an integer when called with the index of

the integer in the array and return the new value and old value back to the user.

$$ A function that adds a new integer to the end of the array input file: $12345678910$
