Assignment 19156

size(), this substr function will cause an out_of_range
exception and terminate the program.
Write an StrExcept exception class that inherits
from the base exception class
out_of_range by defining its own constructor and a print() method outputting a
custom error message to the user.
Then, in the
main method, write a program that asks the user to enter a string before asking
him/her to enter the start index of the substring and its length.
This program
should throw StrExcept if the start index is larger than the size of the string
and handle this exception by surrounding it by try-catch block.
Note that
out_of_range class would require you to include stdexcept library.
Problem2:
Write a
recursive version of the binary search algorithm.
Function prototype:intbSearch(constint a[],int lo, inthi,intx)
Where lo and hi are the indexes of
the first and last element of the binary search.
Note: You
can assume that the items of the searched array to test in your main method are
sorted/
