Data Comparisons

One of the most basic capabilities of any programming language is the ability to make comparisons. There are special symbols used to compare data in programming. The result of every comparison is either true or false.

For example:

5 > 7 is false
7 < 9 is true

Data Comparisons Summary

Making Comparisons
In programming, we compare things using special symbols.
The result is either "true" or "false" – like saying if 5 is greater than 7 (which is false) or if 7 is less than 9 (which is true).
To compare variables (like checking if Mark's balance is the same as Angela's), we use the double equal sign (==) or the exclamation equal sign (!=) for not equal.
Symbols like < (less than) or > (greater than) help us compare numbers.
Combining Conditions
Sometimes we need to check multiple things at once
We use logical operators like && (And) and || (Or).
For example, to check if a balance is between 50 and 100, we write balance > 50 && balance < 100.
These logical operators make our code more readable and allow us to create more complex conditions.
