Question

For c++.

pls help me for my case study T_T

1. Write a program that will arrange the elements of 10-integer array in descending order. (descArray.cpp)

2.Write a program that will ask the name, age, address, and course of a student if the users typed yes. Otherwise, output all the inputted value. Create a function for the input, conditions, and display. (studentInfo.cpp)
Sample Run: Enter a name: Rose Ann
Enter age: 17
Enter address: Calamba, Laguna
Enter Course: BSCS
Do you want to enter another record [Y/N] ? Y

Enter a name: Rose Marie
Enter age: 19
Enter address: Cabuyao, Laguna
Enter Course: BSA
Do you want to enter another record [Y/N] ? Y

Enter a name: Rolando
Enter age: 16
Enter address: Makati City
Enter Course: BSCpE
Do you want to enter another record [Y/N] ? N
