Basic 1. Create a program that calculates the average of several numbers. The user will indicate how many numbers to average. 2. Modify exercise 1: The user will not indicate how many numbers to average at the beginning. Now the user will keep entering numbers until he decides to not enter more. 3. Create a very simple program that gets names of students from the user, one by one, and prints those names. The user will indicate when to stop. Advanced: HINT for exercises 1 and 2: look at the basic exercises. Can you reuse anything? 1. Create a program that calculates the average of grades for a group of students: 1. Each Student will have the same number of grades for the average: 3 2. The number of students is not set from the beginning 3. For each Student the input shoud be the Student name and then all grades obtained 4. After each Student name + his grades were entered the program should print the name of the student together with the average he obtained. 2. Same as exercise 4, but this time each student might have a different number of grades. 3. The Fibonacci sequence starts 1, 1, 2, 3, 5, 8... Each number in the sequence (after the first two) is the sum of the previous two. Write a program that computes and outputs the nth Fibonacci number, where n is a value entered by the user
