To get promotion in a Science stream, a student must pass in English and should pass in any of the two subjects (i.e.; Physics, Chemistry or Maths). The passing mark in each subject is 35. Write a program in a Single Dimension Array to accept the roll numbers and marks secured in the subjects for all the students. The program should check and display the roll numbers along with a message whether "Promotion is Granted" or "Promotion is not Granted". Assume that there are 40 students in the class.
Write a program in Java using arrays:
(a) To store the Roll No., Name and marks in six subjects for 100 students.
(b) Calculate the percentage of marks obtained by each candidate. The maximum marks in each subject are 100.
(c) Calculate the Grade as per the given criteria:Percentage Marks Grade From 80 to 100 A From 60 to 79 B From 40 to 59 C Less than 40 D Write a program to store 20 numbers in a Single Dimensional Array (SDA). Now, display only those numbers that are perfect squares.
