Humans easily get bored doing a repetitive job. However, computers are masters of iteration. In programming, we get a control structure that allows a set of instructions to be executed repeatedly based on a condition. It enables automating repetitive tasks by iterating through a block of code until a specific condition is met or for a defined number of times. What is this control structure called?

 Variable

 Operator

 Loop

 Data Type

The block of code displayed here is meant for the ball, if the value beside repeat would have been 1 instead of 2, Select all the statements that explain the situation.

 The Ball would not have returned to Cat.

 Removing the loop from the code would have made no difference in the result.

 The Ball would not have left its original position.

 The code would throw an error
