Extracted text: Description: Implement function getPercentage that takes two inputs : grade and totalGrade and outputs the grade percentage as follows: percentage = (grade/total grade)*100. (Assume a student can not get a grade above 100%) Define your own exception classes: 1. DivideByZeroException as a derived class of Standard Library class runtime_error, that is used to detect division by zero run time error. 2. NegativeNumberException as a derived class of Standard Library class logic_error, that is used to detect if the user entered a negative number as a grade. 3. InvalidGradeException as a derived class of Standard Library class logic_error, that is used to detect if a user entered an invalid input (grade greater than total grade). Use the above exception classes after implementing them to apply exception handling for your getPercentage function.
