Question

Choose the best type of loop for each situation.

Answer 1

Answer:

1. Option A: for loop is correct

2. Option B: while loop is correct

Explanation:

Two loops are used commonly. For and while

For is used when the number of iterations are already known and while is used when number of iterations is not known and the loop has to be terminated based on any condition.

1. You are finding the batting average of 13 baseball players.

For loop will be used as the number of iterations is already known. The score of 13 players has to be used to calculate the average so there will be 13 iterations. Hence, for loop will be used.

2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday  present. They will show they are done by entering the word "done."

While loop will be used as the termination of loop depends on the input given by the user so the number of iterations are not already known.

Hence,

1. Option A: for loop is correct

2. Option B: while loop is correct
