Write a program that can calculate the class average for a number of students. The user should be able to enter the grades, use sentinel-controlled repetition to manage input. (python) Sample Output: Enter grade, -1 to end: 75 Enter grade, -1 to end: 94 Enter grade, -1 to end: 97 Enter grade, -1 to end: 88 Enter grade, -1 to end: 70 Enter grade, -1 to end: 64 Enter grade, -1 to end: 83 Enter grade, -1 to end: 89 Enter grade, -1 to end: -1 class average is 82.5 2- Write a program that reads in two integers and determines and prints whether the first is a multiple of the second. (Hint: Use the modulus operator.

Python. Match the control structure with the most accurate definition. Example: Conditionals: a) c) and e) Conditionals: Repetition: Functions:     a) A group of statements which can be executed on demand. b) A statement which is executed only of a result of an expression is False c) A statement which is executed only of a result of an expression is True d) A block of code which is executed 0 or more times depending on if the result of an expression in True.  e) A group of statements which are never executed.             f) Something that happens over and over no matter what.

REPETITION CONTROL STRUCTURE (FOR) Instruction: Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant. A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant. The first few perfect numbers are 6, 28, 496, and 8128. Illustrations: Number Factors of the number less than itself Sum of Factors 3, 2, 1 14, 7, 4, 2, 1 6 6 28 28 For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 >1 + 2 + 4, while the number 12 is abundant, since 12<1 + 2 + 3 + 4 + 6. Sample Input/Output: Depicted below are sample outputs when the program is executed (the items in bold characters are input from the user, while the items…
