APCSA Unit 4 Iteration Flashcard

Front

What is iteration in programming?

Back

Iteration is the process of repeating a set of instructions or statements in a program until a certain condition is met.

Front

What is a loop in programming?

Back

A loop is a control structure that allows code to be executed repeatedly based on a condition.

Front

What is the purpose of a for loop?

Back

A for loop is used to execute a block of code a specific number of times, typically with a counter variable.

Front

What is the difference between a while loop and a for loop?

Back

A while loop continues to execute as long as a specified condition is true, while a for loop is typically used when the number of iterations is known beforehand.

Front

What does the term 'increment' mean in the context of loops?

Back

Increment refers to increasing the value of a variable, often used in loops to move to the next iteration.

Front

What is a nested loop?

Back

A nested loop is a loop inside another loop, allowing for more complex iterations over data structures.

Front

What is the output of the following code: for(int i=1; i<=3; i++) { System.out.print(i + ' '); }

Back

The output will be: 1 2 3

Front

What is the role of the break statement in a loop?

Back

The break statement is used to exit a loop prematurely when a certain condition is met.

Front

What is the role of the continue statement in a loop?

Back

The continue statement skips the current iteration of a loop and proceeds to the next iteration.

Front

What is a loop control variable?

Back

A loop control variable is a variable that determines how many times a loop will execute.
