Iteratation

Question 1

While loop

Answer 1

While (condition) {
Statements;
}

Will always run until condition is false

Question 2

Do-while

Answer 2

Loop to be ran prior to condition check and will go back to the top

Do {
Statements;
} while (condition);

Question 3

For loop

Answer 3

Runs for a set number of iterations

For (initialisation; condition; Increase/decrease) {
}
Initialise: initialise the variable used for condition

Condition: checks If loop should be executed or not

Increase/decrease: affects variable to check the condition

For (int counter =1; counter <= 10; counter++) {

}

Question 4

Nested loops

Answer 4

Loop inside loop

Question 5

Break statement

Answer 5

Terminates a loop and code goes back to normal flow, can also be used for switches

EXITS LOOP

Question 6

Continue statement

Answer 6

Skips current iteration and continues to next iteration

I .e if we skip 3 of an iteration we go to irritation number 4

Question 7

When does iteration occur in code?

Answer 7

After statements have occurred.

So read initialisation see if it meets condition, perform statements then iteration
