Variables in Alice 2. Data Type - Computer programs can use and store many different types of data, and each data type will generally serve a specific purpose. In Alice, there are four data types, and you can only store data of the appropriate type in a given variable: a Number - can hold any number integer or real. A local variable can only be used inside the method where it is defined.

Outside the method, it is like the variable does not exist. When the end of the method is reached, the variable ceases to exist. For example, the move to method allows you to specify another object as the destination. This target object is specified using the parameter variable of the move to method. They can be set or modified before or what is right coronary artery dominance program execution.

All objects in the world can see their values, and any method in the world can use or modify the variable. Initial Value The initial value is the starting value placed in the variable.

Always initialize your variables. Create a new world with an instance of the Penguin class Animals. Create a new variable called numberJumps. Initialize numberJumps to 5. Select the Penguin object and find the Method called jump. Drag this method into your programming window, and set the times parameter to be your new variable numberJumps. What do you think should happen?

Play to world to confirm your guess. Save this world as PenguinTutorial Variables in Alice Changing Variables Using the Set Instruction Once you have given an initial value to a variable, it will keep that value throughout the execution of the program. If you want to change the value, you can use a set instruction to specify a new value. To create a set instruction, drag the variable tile at the top of the programming window to the location in the program where you want to make the change.

Exercise 2 Changing a Variable using the Set Instruction. Drag the variable numberJumps into the programming window, below the penguin. Set the value to 2. Copy the penguin. Execute your program.
