Then loaded onto the robot where they can be run. This quiz has been designed to test your knowledge and programming skills. Read the questions carefully and answer. All the best!


Questions and Answers
  • 1. 

    According to the Robot-C video, what is the role of the programmer?

    • A.

      Giving the robot the solution to a problem

    • B.

      Identifying the task, planning a solution, and explaining to the robot what it needs to do to reach the goal

    • C.

      Identify the goal, follow the plan, and program the robot

    • D.

      Tell the robot what to do

    Correct Answer
    B. Identifying the task, planning a solution, and explaining to the robot what it needs to do to reach the goal
    Explanation
    The role of the programmer, according to the Robot-C video, is to identify the task, plan a solution, and explain to the robot what it needs to do to reach the goal. The programmer is responsible for analyzing the problem, determining the steps required to solve it, and providing instructions to the robot on how to execute those steps. This involves understanding the goal and breaking it down into manageable tasks that the robot can understand and perform. The programmer's role goes beyond simply telling the robot what to do; it involves strategic thinking and problem-solving skills to ensure the robot can successfully achieve the desired outcome.

    According to the Robot-C video, what is the role of the robot?

    • A.

      To solve the problem

    • B.

      To do what the programmer wants it to do

    • C.

      To frustrate the programmer

    • D.

      To follow the instructions given to it

    Correct Answer
    D. To follow the instructions given to it
    Explanation
    The role of the robot, according to the Robot-C video, is to follow the instructions given to it. This means that the robot's main purpose is to carry out specific tasks or actions as directed by the programmer. It is designed to adhere to the given instructions and perform the desired actions accurately and efficiently.

  • 3. 

    Pseudocode is…

    • A.

      A language that both the robot and programmer understand

    • B.

      A language that only the robot understands

    • C.

      A programming language that is image based (like Mindstorms)

    • D.

      A hybrid language that is half way between English and the programming language

    Correct Answer
    D. A hybrid language that is half way between English and the programming language
    Explanation
    Pseudocode is a programming language that is designed to be easily understood by both the programmer and the robot. It is a hybrid language that combines elements of English language with programming language syntax. This allows the programmer to write code in a more human-readable format, making it easier to understand and debug. The robot can then interpret and execute the pseudocode instructions to perform the desired tasks.

    White spaces and line breaks are important in programming because…

    • A.

      They separate the commands for the robot to follow

    • B.

      They make the code more readable for the programmer

    • C.

      They identify specific classes of commands

    • D.

      They identify the sequence the robot needs to follow

    Correct Answer
    B. They make the code more readable for the programmer
    Explanation
    White spaces and line breaks are important in programming because they make the code more readable for the programmer. By adding white spaces and line breaks, the code becomes easier to understand and follow, especially when dealing with complex or lengthy code. It helps in organizing the code and separating different sections or blocks of code. Additionally, it improves code maintenance and collaboration among programmers by making it easier to identify and modify specific parts of the code.

    What is the difference between using // and /* */ in your program?

    • A.

      // allow the programmer to insert a note on a single line and /* */ allow the programmer to use more than one line for notes

    • B.

      /* is used at the beginning of a program and */ is used at the end. // is used at the end of a command line

    • C.

      // ends a line of code and /* */ are used for multiple lines of code

    • D.

      /* */ allow the programmer to insert a note on a single line and // allow the programmer to use more than one line for notes

    Correct Answer
    A. // allow the programmer to insert a note on a single line and /* */ allow the programmer to use more than one line for notes
    Explanation
    The correct answer states that using // allows the programmer to insert a note on a single line, while /* */ allows the programmer to use more than one line for notes. This means that // can be used to add comments or explanations to a specific line of code, while /* */ can be used to add comments or explanations that span multiple lines of code.

    What will the robot do when it follows the following commands: 1              task main () 2              { 3              4                        motor[motorC] = -100; 5                        motor[motorB] = 100; 6                        wait1Msec(2000); 7              8              }

    • A.

      Go forward for 20 seconds

    • B.

      Turn on Motor C for 20 seconds

    • C.

      Do a swing turn for 20 seconds

    • D.

      Do a point turn for 2 seconds

    Correct Answer
    D. Do a point turn for 2 seconds
    Explanation
    The robot will do a point turn for 2 seconds because in the given code, the motor[motorC] is set to -100 and motor[motorB] is set to 100. This means that motorC will move in the opposite direction to motorB, causing the robot to turn on the spot. The wait1Msec(2000) command indicates that the robot will wait for 2000 milliseconds, which is equal to 2 seconds. Therefore, the robot will perform a point turn for 2 seconds.

    What will the robot do when it follows the following commands: 1              task main () 2              { 3              4                        motor[motorC] = -50; 5                        motor[motorB] = -50; 6                        wait1Msec(5000); 7              8              }

    • A.

      Go forward at half speed for 5 seconds

    • B.

      Go forward for 50 seconds

    • C.

      Reverse at half speed 5 seconds

    • D.

      Reverse for 50 seconds

    Correct Answer
    C. Reverse at half speed 5 seconds
    Explanation
    The given code snippet is a part of a program for a robot. In the program, the motors for motorC and motorB are set to a speed of -50, which indicates reverse motion. The wait1Msec(5000) command pauses the program for 5 seconds. Therefore, the robot will reverse at half speed for 5 seconds.

  • 11. 

    What will the robot do when it follows the following commands: 1              task main () 2              { 3              4                        motor[motorC] = -75; 5                        motor[motorB] = 0; 6                         7                        motor[motorC] = 0; 8                        motor[motorB] = 0; 9                        wait1Msec(3000); 10 11              }

    • A.

      A point turn and stop for 30 seconds

    • B.

      Nothing

    • C.

      A swing turn and stop for 3 seconds

    • D.

      A swing turn for 30 seconds and then stop

    Correct Answer
    B. Nothing
    Explanation
    The robot will do nothing because the motors are set to 0 in lines 5 and 8, and there are no other commands given to the motors. Additionally, there is a wait1Msec(3000) command in line 9, which means the robot will wait for 3 seconds before continuing to the next command, but there are no further commands after the wait. Therefore, the robot will simply do nothing.

  • 12. 

    Control structures such as task main or if-else:

    • A.

      Issue direct commands to the robot’s motors

    • B.

      Are only there for the human programmer’s benefit, and are ignored by the robot

    • C.

      Control the “flow” of commands: they choose which commands to run and when

    • D.

      Are a form of paired punctuation

    Correct Answer
    C. Control the “flow” of commands: they choose which commands to run and when
    Explanation
    Control structures such as task main or if-else control the "flow" of commands: they choose which commands to run and when. They determine the sequence and conditions under which different commands are executed by the robot. These control structures are essential for programming the robot to perform specific tasks and make decisions based on certain conditions. They play a crucial role in directing the overall behavior and functionality of the robot.
