Arrays are an important part of any programming language as they let us group together and manipulate a large amount of similar data. In this section we will learn about Arrays and how to use them for practical applications.

6. Methods

In this section we will learn about one of of the most widely used and essential features of C# called Methods. We will also explore its uses through creative practice tasks.

Order of Operations

In case there's only one operator used multiple times then the expression is evaluated from left to right.

For the examples we will use true and false literals for simplicity. In case we have a long expression like false || false || true || false, the expression will be evaluated from the left side:

main.cs

Following is a more complex example which includes multiple different operators. It will be a good code reading exercise to read and try to understand it:

main.cs

In the above code, we have the expression (1 <= x) && (x <= 10) || (90 <= x) && (x <= 100), which checks if x is in the range 1-10 or 90-100.

The order of the logical operators is the following:

Considering the order of operators, the expression will be evaluated as follows:
