What is the purpose of an if statement in Go?

An if statement lets the program decide to run some code only if a condition is true. It's like choosing a path based on a yes/no question.

beginner

How do you write a simple if statement in Go?

You write if condition { /* code to run if true */ }. The condition follows directly after if without parentheses, and the code to run is inside curly braces.

Can you use an if statement without an else in Go?

Yes! You can run code only when the condition is true and do nothing if it is false. The else part is optional.

What happens if the if condition is false and there is no else block?

The program skips the code inside the if block and continues running the rest of the program.

How do you write an if-else statement in Go?

You write if condition { /* code if true */ } else { /* code if false */ }. This runs one block or the other depending on the condition.

What does an if statement do in Go?

A Runs code only if a condition is true

An if statement checks a condition and runs code only when it is true.

The else block is optional; you can have just an if statement.

What happens if the if condition is false and there is no else?

A Program crashes

B Code inside <code>if</code> runs anyway

D Code inside <code>if</code> is skipped

If the condition is false and no else exists, the code inside if is skipped.

How do you write an if-else statement in Go?

A if (condition) then { } else { }

C if condition: { } else: { }

D if condition -> { } else -> { }

The correct syntax is if condition { } else { } without extra words or symbols.

Explain how an if statement controls the flow of a Go program.

Think about how you decide to do something only if a condition is met.

Write the syntax of a simple if statement in Go and describe each part.

Remember the shape of the code with braces and the condition.
