Today: Lab Assignment ONLY. THERE ARE TWO BONUS QUESTIONS and ONE CHALLENGE!! You can make up your quiz 3 grade!

Program 1 (100 points)

• Write a program that doing statistic analysis of the grades. This program is similar to the program that we learned in class. The input consists of integer that indicates the amount of students in class, and the sequence of integers that follow the first input. Each integer in the sequence indicates the grade of the students and the amount of integers in the sequence equals to the first integer. The program finds the amount of students who failed the class, the amount of students who passed the class, the amount of students who got grade A (A: 95 - 100), and the average of passing grades and the average of failing grades. The programn prints the output with descriptive messages.
• Compile and Run your program , show me the result

Program Bonus 1 (10 points)

• Write a program that first reads one positive integer that will indicate an amount of input integer numbers that will come after that. The program will read the series of the integer numbers (amount of integer numbers will be equal to the first input number) and will find the sum of the positive input numbers.
  Fore example is the input was 3, 4 -5 6 the program should output 10 (4+6)(the first input number, 3, indicates the amount of the input numbers that will be entered after that number.
• Compile and run your program. Show me the result

BONUS Program 2 10 points

• Write a program that inputs a series of 10 integers, and determines and prints the amount of positive, negative and zero numbers among 10 input numbers.
• Compile and Run your program , show me the result

CHALLENGE Program

Write a program that reads the 9 distinct integers from 1 to 9 and prints them out in the following way: each integer will be printed the number of times equal to its numeric value. Each such repeated output will be printed on a different line. The nine input integers may be input in any order. You may assume that correct input is always given.
See example below.
Example :
Input: 1 2 3 4 5 6 7 8 9
Output:
1
22
333
4444
55555
666666
7777777
88888888
999999999

Have a good evening.
