Question

write a program named testsinteractive that prompts a user to enter eight test scores and displays the average of the test scores to two decimal places.

Answer 1

This programming task involves creating a program to calculate and display the average of eight test scores entered by the user, rounded to two decimal places using programming constructs such as loops, input/output functions, and arithmetic operations.

Step-by-step explanation:

The problem asks for a program that prompts a user to enter eight test scores, calculates the average of these scores, and displays the result rounded to two decimal places. This entails using programming constructs such as input/output functions, loops, and arithmetic operations to sum and average the numbers. After obtaining the average, the program should format the result to show only two decimal places before displaying it to the user.

To accomplish this task, one may use a variety of programming languages such as Python, Java, or C++. The specific steps include: initializing a total variable, using a loop to collect the eight test scores from the user, summing these scores, dividing by the number of scores to get the average, and finally formatting the average to two decimal places using the appropriate formatting command or function in the chosen programming language.

For example, in Python, the round function can be used to format the average to two decimal places before outputting it with the print function. Additionally, the Python input function would be used to collect each of the test scores from the user within a loop construct.

Answer 2

A program named testsinteractive can be created using Python to prompt for eight test scores, calculate the average, and display it rounded to two decimal places. The code includes collecting scores in a loop, computing the average, and formatting the output.

Step-by-step explanation:

To create a program named testsinteractive that calculates the average of eight test scores, you can use a programming language such as Python. The program will prompt the user for eight test scores, compute the average, and then display the result, rounded to two decimal places. Here is a simplified example of how such a program could look:

scores = []
for i in range(8):
score = float(input("Enter test score #" + str(i + 1) + ": "))
scores.append(score)
average_score = sum(scores) / len(scores)
print("Average test score: {0:.2f}".format(average_score))

This code snippet uses a loop to collect eight scores, adds them to a list, then calculates the average using the sum function and list's length. The average test score is then displayed with two decimal precision.
