Question $2(30$ points$)$: Implement a C$++$ program that performs a sequential search on an array of $20$

integers to find a specific value entered by the user. If the value is found, print its index; if not, print a

message indicating that the value was not found. Ensure that your program can handle large arrays and

invalid inputs gracefully.

Sample Test Case:

Input Array: $71428354256637791105119133147161175189203217231245$

Search Value: $91$

Output: The value $91$ is found at index $8.$
