Write a program that prompts the user for number of students to process. The program will allow the user to enter the name of student and then it will ask for the number of marks for that student. The program will then prompt for each score and will calculate the average mark for each student.

Sample Run:

Enter number of students: 2

Enter student 1 name: Jenny

Enter number of marks for Jenny: 2

Enter mark 1: 99

Enter mark 2: 88

Enter student 2 name: Kevin

Enter mark 1: 75

Enter mark 2: 76

Enter mark 3: 78

=============================

Student 1: Jenny

Marks: 99 88

Average for Jenny is: 93.5%

=============================

Student 2: Kevin

Marks: 75 76 78

Average for Kevin is: 76.3333%

Create a C++ program using conditional statement. Read the worded problem below.

Supposed we have a client, he/she wanted you to create a program for his/her business.

He/She wanted to record the employee’s information. Now, on programmer’s side (You), we

have 3 buttons, the ADD, UPDATE, DELETE.

An ordinary colored printer can print 12 pages per minute. Make a program that will input number of pages, and compute the time to complete the print out. Consider the minutes and hour of your display. Your program will terminate if you input zero in the number of pages.

Ex: Input pages: 720

Minutes = 60

Hour = 1
