If–else statement in Go - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of an if–else statement in Go?

An if–else statement lets the program choose between two paths based on a condition. If the condition is true, it runs one block of code; if false, it runs another.

How do you write a simple if statement in Go?

Use the keyword if followed by a condition, then a block of code in curly braces. Example:<br>

if x > 10 {
    fmt.Println("x is greater than 10")
}

beginner

What is the syntax for an if–else statement in Go?

You write if with a condition and code block, then else with another code block. Example:<br>

if x > 10 {
    fmt.Println("big")
} else {
    fmt.Println("small")
}

Can you use multiple conditions with if–else in Go?

Yes, you can chain conditions using else if to check many cases. Example:<br>

if x > 10 {
    fmt.Println("big")
} else if x == 10 {
    fmt.Println("equal")
} else {
    fmt.Println("small")
}

beginner

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

If the if condition is false and there is no else, the program just skips the if block and continues running the next code.

What keyword starts an if condition in Go?

A when

B if

C condition

D check

The keyword if is used to start a condition check in Go.

What does the else block do in an if–else statement?

A Repeats the if block

B Runs code if the if condition is true

C Ends the program

D Runs code if the if condition is false

The else block runs only when the if condition is false.

Which of these is the correct way to write an if statement in Go?

A if x > 5: fmt.Println("yes")

B if (x > 5) then { fmt.Println("yes") }

C if x > 5 { fmt.Println("yes") }

D if x > 5 do { fmt.Println("yes") }

Go uses if with condition and curly braces for the code block, no extra keywords like then or do.

How do you check multiple conditions in Go?

A Use else if between if and else blocks

B Use multiple if statements without else

C Use switch only

D Use for loops

You chain conditions with else if to check multiple cases in order.

What happens if the if condition is true and there is an else block?

A Only the if block runs, else block is skipped

B Both if and else blocks run

C Only else block runs

D Program crashes

When the if condition is true, only the if block runs; the else block is skipped.

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

Think about choosing between two paths based on a yes/no question.

Write a simple Go if–else statement that prints "Even" if a number is even, and "Odd" if it is odd.

Use x % 2 == 0 to check even numbers.
