bookOrder 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:

cs

main

copy
123456789101112
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { Console.WriteLine(false || false || true || false); // Output: True } } }

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:

cs

main

copy
1234567891011121314151617181920
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { int x = 50; // We can store results of boolean / logical expressions in boolean variables or constants. bool inRange = (1 <= x) && (x <= 10) || (90 <= x) && (x <= 100); Console.WriteLine($"The value {x} is in the range 1-10 or 90-100: {inRange}"); // Output: False x = 99; inRange = (1 <= x) && (x <= 10) || (90 <= x) && (x <= 100); Console.WriteLine($"The value {x} is in the range 1-10 or 90-100: {inRange}"); // Output: True } } }

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:

Which operator is evaluated first?
