Task - Operators - Ternary Operator

[akash-coded]

WAP using ternary operators that calculates the grade of a student based on the marks entered by the user in three subjects.

The program prints the passed/failed status of the student based on the following logic:

• If the average of marks is >= 40, then print Passed
• Else print Failed

The program prints the grade of the student based on the following logic:

• If the average of marks is >= 80 then prints Grade ‘A’
• If the average is < 80 and >= 60 then prints Grade ‘B’
• If the average is < 60 and >= 40 then prints Grade ‘C’
• else prints Grade ‘D’
