Write a program to store 20 numbers in a Single Dimensional Array (SDA). Now, display only those numbers that are perfect squares.
| n[0] | n[1] | n[2] | n[3] | n[4] | n[5] | … | n[16] | n[17] | n[18] | n[19] |
|---|---|---|---|---|---|---|---|---|---|---|
| 12 | 45 | 49 | 78 | 64 | 77 | … | 81 | 99 | 45 | 33 |
Sample Output: 49, 64, 81

The annual examination result of 50 students in a class is tabulated in a Single Dimensional Array (SDA) is as follows:
Roll No. Subject A Subject B Subject C ……. ……. ……. ……. ……. ……. ……. ……. ……. ……. ……. ……. Write a program to read the data, calculate and display the following:
(a) Average marks obtained by each student.
(b) Print the roll number and the average marks of the students whose average is above. 80.
(c) Print the roll number and the average marks of the students whose average is below 40.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.
