Loop execution flow in Go - Cheat Sheet & Quick Revision

Recall & Review

What is the basic structure of a for loop in Go?

A for loop in Go has three parts: initialization, condition, and post statement. It looks like:

for i := 0; i < 5; i++ { /* code */ }

What happens when the condition in a Go for loop becomes false?

The loop stops executing and the program continues with the code after the loop.

How does the continue statement affect loop execution in Go?

The continue statement skips the rest of the current loop iteration and moves to the next iteration immediately.

intermediate

What does the break statement do inside a Go loop?

The break statement immediately exits the loop, skipping any remaining iterations.

intermediate

Can a Go for loop run forever? How?

Yes. If the loop condition is omitted or always true, the loop runs forever. Example:

for { /* infinite loop */ }

What part of the Go for loop controls how many times it runs?

A The condition expression

B The initialization statement

C The post statement

D The loop body

The condition expression is checked before each iteration. If false, the loop stops.

What does the continue statement do inside a Go loop?

A Stops the loop completely

B Skips to the next iteration

C Restarts the program

D Exits the current function

Continue skips the rest of the current iteration and moves to the next one.

Which statement immediately exits a Go loop?

A continue

B exit

C break

D stop

The break statement exits the loop immediately.

What happens if you omit the condition in a Go for loop?

A The loop runs forever

B The loop runs once

C The loop runs zero times

D The code will not compile

Omitting the condition makes the loop run forever (infinite loop).

In Go, which part of the for loop runs after each iteration?

A Initialization

B Condition

C Loop body

D Post statement

The post statement runs after each iteration, often used to update the loop variable.

Explain how the flow of execution works in a Go for loop from start to finish.

Think about the order of the three parts and when the loop body runs.

Describe the difference between break and continue statements in Go loops.

One stops the loop, the other skips to the next round.
