4.3.6 ?All Star CodeHS
Write a program that gets three variables from the user, their points per game, their rebounds per game, and their assists per game, in that order.
We need to figure out if the user is an all star. They are an all star if they got at least 25 ?points per game, OR they got at least 10 ?points, at least 10 ?rebounds, and at least 10 ?assists. You will need to use both logical and comparison operators here.default.js
function start(){
var pointsPerGame = ?readint (“Points per game?”);
var reboundsPerGame = ?readInt(“Rebounds per game? “);
var assistsPerGame = ?readInt (“Assists per game?”);
var isAllstar = ?pointsPerGame =25|| ?pointsPerGame =10 ?&& reboundsPerGame =10 ?&& assistsPerGame =10;
printIn(“Is all star?” + ?isAllstar);
The correct answer and explanation is:
Here’s how to approach this problem correctly:
Steps for the program:
- Read the inputs: You need to ask the user for their points per game, rebounds per game, and assists per game.
- Check conditions:
- The user qualifies as an “All Star” if:
- They have at least 25 points per game, OR
- They have at least 10 points, 10 rebounds, and 10 assists per game (this is an AND condition).
- The user qualifies as an “All Star” if:
- Print the result: You need to print whether the user qualifies as an All Star.
Fixed Code:
function start() {
// Prompt user for input
var pointsPerGame = readInt("Points per game?");
var reboundsPerGame = readInt("Rebounds per game?");
var assistsPerGame = readInt("Assists per game?");
// Check if the user qualifies as an All Star
var isAllStar = pointsPerGame >= 25 || (pointsPerGame >= 10 && reboundsPerGame >= 10 && assistsPerGame >= 10);
// Print the result
printIn("Is All Star? " + isAllStar);
}
Explanation:
- Variables and Input:
pointsPerGame,reboundsPerGame, andassistsPerGameare used to store the points, rebounds, and assists per game respectively. We use thereadInt()function to capture user input for each of these statistics.
- Logic to Determine All Star Status:
- The main part of this problem is the logical check. We have two conditions to evaluate:
- Condition 1:
pointsPerGame >= 25. This checks if the player has at least 25 points per game. - Condition 2:
(pointsPerGame >= 10 && reboundsPerGame >= 10 && assistsPerGame >= 10). This checks if the player has at least 10 points, 10 rebounds, and 10 assists.
- Condition 1:
- If either condition is true, the player qualifies as an “All Star.” This is handled by the logical OR (
||) between the two conditions.
- The main part of this problem is the logical check. We have two conditions to evaluate:
- Printing the Result:
- The program outputs
trueif the user qualifies as an All Star, andfalseotherwise. This is done usingprintIn("Is All Star? " + isAllStar).
- The program outputs
Why It Works:
- Comparison Operators: These are used to compare the user’s statistics against the thresholds (25 for points or 10 for points, rebounds, and assists).
- Logical Operators: The OR (
||) operator ensures that if either condition is satisfied, the user is an All Star. The AND (&&) operator ensures that all three statistics (points, rebounds, and assists) must be at least 10 for the second condition.
By structuring the conditions correctly and ensuring the logical flow is clear, this program accurately determines if a user is an All Star based on their performance stats.
Example Inputs and Outputs:
- Input 1: Points per game = 30, Rebounds per game = 5, Assists per game = 8 → Output:
true(points >= 25). - Input 2: Points per game = 8, Rebounds per game = 12, Assists per game = 15 → Output:
true(points, rebounds, and assists all >= 10). - Input 3: Points per game = 5, Rebounds per game = 5, Assists per game = 5 → Output:
false.
