design a program for a professor to calculate the average of the three test scores for the students and congratulate the student enthusiastically if the average is greater than 95. here is the algorithm below. write the pseudocode for this program: 1. get the first test score. 2. get the second test score. 3. get the third test score. 4. calculate the average. 5. display the average. 6. if the average is greater than 95, congratulate the student.
Scenario: A robot is sitting in a chair with its arms facing down. Write an algorithm, using pseudocode, to make the robot:
stand up
walk until it senses a wall
turn around
walk back to the chair
sit back down in the origin starting position
Finally, output the total number of steps taken.
Commands:
In addition to our standard pseudocode commands, you must also use the following robot control commands:
sit
stand
step (one step forward)
raise arms (parallel to floor)
lower arms (pointing to floor)
sense (only if arms are raised)
turn (90 degrees right)
Immediately after issuing a sense command, you can check if the robot is at a wall.You do this via the boolean conditions "at wall" or "not at wall".The following are examples of this:
if at wallif not at wallwhile not at wall
AssumptionsYou must assume the following facts:
The robot's initial sitting position is directly facing the target wall.
There are no obstacles between the robot and the wall.
The wall is 1 or more exact steps…
The following program moves a robot in a grid of squares. The initial position and direction of the robot is shown below. Click on the grid to move the robot to the final position after the program is run. You must click within the box to rotate the robot to the correct final direction (click near the top of the box to rotate up, etc...) Feel free to move the robot along as you follow the code.
PROCEDURE DoSomething(a){ MOVE_FORWARD() if( a > 2 ) { MOVE_FORWARD() } else { if( a = 3 ) { MOVE_FORWARD() } } MOVE_FORWARD()}

- Make a program that asks for a width, and then prints a pyramid of that width. The pyramid must be of odd width, and if the user enters an even number the program should print "Please enter an odd number" and ask again. (It is ok if the program gives an error if the user enters a non-number). Example: Please enter the pyramid width 10Please enter an odd numberPlease enter the pyramid width 14Please enter an odd numberPlease enter the pyramid width 13 * *** ***** ******* ********* ************************ The first line should have 1 asterisk, the second 3, then 5, 7, 9 etc. The number of spaces before starting the asterisks is (n−i)/2 Where n is the width of the pyramid and i is the number of asterixes in the current line. Note that this is always a whole number, as n and i are odd and hence (n-i) is even.arrow_forwardDesign an algorithm that will receive two integer items from a user, and display to the screen their sum, difference, product and quotient.
