write a program in C++ in Eclipse

Practice Example 4: Write a program that prompts the user to enter the number of students n in the class then reads it. It should then ask the user again to enter the n grades for the students, one by one Finally, your program should compute and print the average grade of the class. Code: \#include > using namespace std; int main0 \{ return 0 ; Sample Output: Enter the no. of students in the class: 5 Enter student no. 1 grade: 25 Enter student no. 2 grade: 23 Enter student no. 3 grade: 24 Enter student no. 4 grade: 25 Enter student no. 5 grade: 24 The average class grade is: 24.2 Sample Output: Enter weight in kg: 10 Error: Negative weight! Re-enter: 7 Error: Negative weight! Re-enter: 5 Error: Negative weight! Re-enter: 2 Error: Negative weight! Re-enter: 10 Weight in lbs is: 22 Practice Example 8: Create a function with bool return type that checks whether your KCST ID is even or Odd number. Sample Output: Enter your KCST ID : 185123 Your KCST ID is OD Code: \#include > using namespace std; bool fun(int ID) \{ int main 0 f int ID; retum 0
