Write code to find the grade of a student given their score as follows:

• 85 <= Excellent <= 100
• 75 <= Very Good < 85
• 65 <= Good < 75
• 50 <= Pass < 65
• 0 <= Fail < 50

Note: A score greater than 100 or less than 0 is not a valid score and should return a message Not valid

Edit the getGrade( ) function in the main.cpp file. The function takes the score as input and returns a string grade as the output. Do not write a main function. Only edit the part marked with \\ Write your code here
