Variables and data storage in Intro to Computing - Draw & Build Visually

Draw This - beginner

Draw a memory diagram showing how the variables A, B, and C store the values 10, 25, and 7 respectively. Label each variable with its name and value, and show the memory addresses as boxes.

Grading Criteria

Three separate boxes representing memory addresses

Each box labeled with a unique memory address

Each box contains a variable name (A, B, C)

Each variable box shows the correct value (10, 25, 7)

Boxes are clearly separated and labeled

Solution

Memory Diagram:

+---------+       +---------+       +---------+
| Address |       | Address |       | Address |
|  1001   |       |  1002   |       |  1003   |
+---------+       +---------+       +---------+
|   A=10  |       |   B=25  |       |   C=7   |
+---------+       +---------+       +---------+

This memory diagram shows three boxes representing memory locations at addresses 1001, 1002, and 1003.

Each box is labeled with the variable name (A, B, C) and the value stored inside (10, 25, 7 respectively).

This illustrates how variables are like labeled containers in memory holding data values.

Variations - 2 Challenges

[intermediate] Draw a memory diagram for variables X, Y, and Z storing the values 3.14, 'hello', and 42 respectively. Include memory addresses and labels.

[advanced] Draw a memory diagram showing variables M, N, O, and P storing values 5, 10, 15, and 20. Show memory addresses and indicate which variables hold even numbers.
