C#作业求助：成绩平均值计算程序逻辑梳理指引

Hey there! I get that sorting out the logic for this assignment can feel tricky at first—let's break it down into simple, actionable steps to get you moving forward:

• First, tackle input parsing:

  • Start by reading the entire input line from the user.
  • Split that input into separate components. The first value is N (your student count), and the rest are the grades. Keep an eye on the input format—since grades are separated by commas, you'll need to split on commas and probably trim any extra whitespace from each part.
  • Convert N from a string to an integer. Then, convert each grade string to a numeric type (like int or double)—and don't forget to make sure each grade falls between 0 and 100 if your assignment requires validation.

• Next, calculate the total sum:

  • Initialize a variable to hold the total sum of all grades (start it at 0).
  • Loop through each of the valid grades you collected, adding each one to the sum variable.

• Compute the average:

  • Divide the total sum by the number of grades you're averaging. Double-check your assignment here: are you calculating the average of all grades combined, or the average per student (if each student has multiple grades)? Make sure you use the correct divisor here.

• Finally, display the result:

  • Output the calculated average. You might want to format it to a specific number of decimal places (like 2) for readability—C# has built-in methods to help with that.

A quick tip: If you're unsure about any step, try writing out the logic in plain English first before translating it to code. For example, "Take the input, split into parts, get N, get all grades, add them up, divide by count, show the number." That can make translating to code much easier.
