Scala & Spark-Master Big Data with Scala and Spark - Solution(For Loop)

The video tutorial guides viewers through writing a program that calculates grades based on user input. It covers taking input for the number of courses, using loops to gather marks, maintaining a cumulative sum, calculating the average, and assigning grades based on the average. The tutorial emphasizes checking code functionality at each step and offers tips for using loops and conditionals effectively.

What is the first step in writing a program to calculate grades based on course marks?

• Assign a grade based on marks

• Ask the user to enter the number of courses

• Ask the user for their name

• Calculate the average marks

How should the number of courses entered by the user be processed?

• Convert it to a float

• Convert it to a string

• Leave it as is

• Convert it to an integer

What is the purpose of using a loop in the program?

• To gather marks for each course

• To calculate the total number of courses

• To display the final grade

• To print the course names

What is the cumulative sum used for in the program?

• To determine the number of courses

• To keep track of the total marks

• To calculate the average marks

• To store the highest mark

How is the average mark calculated in the program?

• By subtracting the lowest mark from the total

• By adding all the marks together

• By dividing the total marks by the number of courses

• By multiplying the total marks by the number of courses

What is the next step after calculating the average marks?

• End the program

• Ask the user for more marks

• Print the total marks

• Assign a grade based on the average

Which condition is checked first in the grading logic?

• If average marks are greater than 70

• If average marks are greater than 90

• If average marks are greater than 50

• If average marks are greater than 60

What grade is assigned if the average marks are greater than 70 but less than 90?

• A grade

• B grade

• C grade

• D grade

What happens if the average marks are less than 50?

• The student receives a B grade

• The student receives a C grade

• The student receives a D grade

• The student receives an F grade

What is the final step in the program after assigning a grade?

• Ask for more courses

• End the program

• Print the average marks

• Recalculate the average
