golang switch no condition

In Go (or golang), the switch statement can be used without a condition. Instead, it allows cases to be evaluated based on the value of the expression following the switch keyword.

Here are the steps involved when using a switch statement without a condition in Go:

1. The switch keyword is used to indicate the start of the switch statement.

2. After the switch keyword, we have the expression that will be evaluated to determine which case to execute.

3. Each case statement is followed by a specific value or a list of values that will be compared against the expression.

4. If the expression matches any of the values specified in a case statement, the corresponding block of code is executed.

5. If none of the case statements match the expression, the default case (if provided) will be executed. The default case is optional and is used when none of the other cases match.

6. After a case block is executed, the switch statement is exited, unless a fallthrough statement is used. The fallthrough statement allows execution to continue into the next case block, even if it doesn't match the expression.

7. If the switch statement is used without a condition, it is often referred to as a "switch true" statement. This means that the value of the expression is not explicitly specified, and the cases are evaluated based on their conditions.

8. It's important to note that in a switch statement without a condition, the order of the case statements matters. The first case that matches the expression will be executed, and the subsequent cases will be ignored.

That's a brief explanation of how a switch statement without a condition works in Go. It provides a flexible way to evaluate cases based on the value of an expression.
