Mastering For Loops

What is the purpose of a loop control statement in a for loop?

• To define the data type of the loop variable.

• To increase the speed of the loop execution.

• To initialize the loop variable only once.

• To manage the iteration process and control the number of loop executions.

What factors can affect the performance of a for loop?

• The color of the loop variable

• Factors affecting for loop performance include loop body complexity, number of iterations, operation efficiency, data structure type, and execution environment.

• The programming language used

• The length of the code editor

What is the output of the following for loop: 'for i in range(5): print(i)'?

• 5

• -1

• 10

• 0 1 2 3 4

What is the role of the loop variable in a for loop?

• It acts as a counter to track the current iteration.

• It determines the number of iterations.

• It defines the data type of the loop's output.

• It stores the final output of the loop.

How can you optimize a for loop for better performance?

• By reducing the number of iterations and simplifying the loop body.

• By adding more print statements within the loop.

• By increasing the number of iterations.

• By using more complex data structures.

What will be the result of the following for loop: 'for i in range(3): print(i * 2)'?

• 0 1 2

• 0 2 4

• 0 1 2 3 4 5

• 0 2 4 6
