Slide 3: What are Constants?
Constants are similar to variables but their values cannot be changed once defined. They are used when a value needs to remain constant throughout the program.

Slide 4: Types of Constants
Constants can have the same types as variables, such as integers, floats, strings, and booleans. The difference is that their values remain fixed.
