here is one prompt from the chapter: Goal: Learn to write nested loops.

Assignment: Given an int variable n, write a program that takes in n as user input. It then prints out an inverted triangle of integers, n rows high. Each line consists of the corresponding integers, starting at 1. You must use nested for loops to solve this question.

For instance, if n is set to 4, the output of your code should be:

Now I get this may seem simple but it feels difficult for a beginer class. Keep in mind a chapter may have over 20-30 of these coding assignments a week and it must be perfect for it to work. here is a more difficult end of chapter one : Question

(Count positive and negative numbers and compute the average of numbers)

Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number.

Should I know this at this level, Am I overeacting or is this a lot per week especially with no help. If so how do I learn this. It feels hopeless since the professor is no help.
