Evan wants to have code in a game that will make it possible to change the speed of a swimmer in the game which of these does Ivan need?

Question

A.a boolean value b. Output c. A variable d. A database

Answer 1

C. A variable.

In order to change the speed of a swimmer in the game, Evan would need to use a variable to store and manipulate the speed value. A variable allows the program to store and modify data as needed. The other options (a boolean value, output, and a database) are not directly related to the specific task of changing the speed of a swimmer in the game.
